The best convention hotels in Barcelona: a comparison with verified data

For a residential convention, the hotel is the decision that shapes everything else: budget, logistics, atmosphere and even the kind of social programme you can run. Barcelona has plenty of hotels with meeting rooms, but few that can accommodate hundreds of people and bring them together in a single plenary. This comparison covers the large convention hotels using data published by the hotel groups themselves or by the Barcelona Convention Bureau, and explains how to choose according to your format.

Barcelona convention hotels compared

Data checked on 14 October 2026 in the sources listed. Capacities depend on the layout (theatre, banquet, cocktail): always confirm them against the room plan. "n/a" means the official source does not publish the figure.

Two notes on the data:

• SOFIA Barcelona is the former Gran Hotel Princesa Sofía. The figures come from the announcement of its addition to The Unbound Collection by Hyatt in 2018. If your convention depends on them, confirm them with the hotel.
• Hyatt Regency Barcelona Tower: the hotel group publishes the meeting space and the capacity of the Cosmos Ballroom, but not the number of bedrooms. The figure of 280 bedrooms comes from AMI Magazine.

How to choose a hotel by format and group size

There is no "best hotel" in the abstract. There is the best hotel for your format, your number of attendees and what you want them to feel when they arrive.

If your group exceeds 1,000 or 1,500 people in plenary, compare with a congress centre too: we explain how in our comparison of Barcelona congress centres.

Which area should your group stay in?

The area sets the atmosphere of the convention and decides how much time the group will spend on a coach.

The hotels, one by one

Hotel Arts Barcelona

A seafront tower in the Vila Olímpica, next to Port Olímpic. With 483 bedrooms, 20 meeting rooms, 2,970 m² of meeting space and a maximum capacity of 1,400 people, according to Marriott, it is one of the most complete options for high-profile conventions. It works well when the convention combines a plenary, working sessions and a gala dinner in the hotel itself. In production terms, book the outdoor areas for cocktail receptions well ahead and plan a plan B for wind.

W Barcelona

The sail-shaped building at the end of Barceloneta. It has 473 bedrooms, 19 meeting rooms and 3,432 m² of meeting space; its largest room measures 987 m² and the maximum capacity is 850 people. It suits conventions of 150 to 600 people looking for a contemporary atmosphere and sea views. As it sits at the end of the promenade, plan with the hotel where coaches will stop and stagger group arrivals and departures.

Leonardo Royal Barcelona Forum (formerly AC Hotel Barcelona Forum)

In Diagonal Mar, next to the CCIB. With 368 bedrooms, 16 meeting rooms and 2,022 m², it is a practical option for accommodating delegates at a CCIB congress or for mid-sized conventions that do not need a 5-star hotel. Maximum capacity of 670 people according to the data Marriott published when it was an AC Hotel.

Hilton Diagonal Mar Barcelona

Also in Diagonal Mar, on Passeig del Taulat, a few minutes from the CCIB. It has 433 bedrooms and 22 meeting rooms, with a 1,001 m² Ballroom for 1,000 people (800 theatre-style), according to its listing with the Barcelona Convention Bureau. It suits conventions of 300 to 800 people and works as the main hotel for congresses at the CCIB. The CCIB states that there are around 4,500 hotel rooms in its surroundings.

Torre Melina, a Gran Meliá Hotel

This is the former Hotel Rey Juan Carlos I on the Diagonal, reopened in 2024 after four years closed, with 391 rooms and suites according to Hosteltur. Meliá advertises 22 meeting rooms and 2,758 m² of meeting space in the hotel, plus direct access to the Palau de Congressos de Catalunya, with an auditorium for more than 2,000 people and 39 rooms. It is the most complete hotel plus congress centre combination in the city for large conventions that want everything under one roof. Note: the Palau de Congressos de Catalunya (Diagonal) is not the same as the Palau de Congressos de Barcelona (Montjuïc), which belongs to Fira.

Hyatt Regency Barcelona Tower

A tower on Gran Via in L'Hospitalet, near Fira Barcelona Gran Via. Hyatt advertises 4,000 m² of multipurpose space, 20 meeting rooms and the Cosmos Ballroom, with capacity for up to 1,800 people theatre-style. It is the natural choice for events linked to trade shows at Gran Via and for large conventions in a business setting. The atmosphere is more corporate than Mediterranean: if you want "Barcelona", bring it into the dinners.

SOFIA Barcelona, The Unbound Collection by Hyatt

The former Gran Hotel Princesa Sofía, on the Diagonal, near the Palau de Congressos de Catalunya and the university area. In 2018, when it joined The Unbound Collection by Hyatt, it announced 465 bedrooms, 22 multifunctional rooms over two floors and a convention hall for more than 1,000 people. It suits large conventions that want the hotel and plenary in the same building in the upper Diagonal area.

Meliá Barcelona Sarrià

In the upper part of the city, near the Diagonal. Meliá advertises almost 2,000 m² of meeting space (1,914 m²), with two multifunctional plenary rooms and 16 breakout rooms; the Sala Barcelona holds up to 550 people. A good option for conventions of 150 to 500 people that need many working rooms.

Hotels where we have produced events

As well as these large convention hotels, in and around Barcelona we have produced events at hotels such as the Hotel Miramar Barcelona on Montjuïc (Edenred's E-Day), the Meliá Barcelona Sky (Meliá's welcome party for IBTM Hosted Buyers) and hotels in Sitges for Edenred and Duscholux conventions. You can see these projects in our case studies.

Convention hotel or congress centre?

In Barcelona, two combinations offer the best of both: Torre Melina with the Palau de Congressos de Catalunya, and the Diagonal Mar hotels with the CCIB.

Site inspection checklist

• Plan of each room with dimensions, clear height, pillars and rigging points.
• Real capacity in your layout (theatre, classroom, banquet, cocktail), not the theoretical maximum.
• Loading access, goods lifts and set-up and breakdown times.
• Available electrical power and the cost of the hotel's in-house technicians.
• Whether you can bring in an external AV supplier, and on what terms.
• Distance between the plenary, breakout rooms and lunch area.
• Natural light and whether rooms can be blacked out.
• Wifi: dedicated bandwidth for the event.
• Accessibility for people with reduced mobility.
• Registration area and cloakroom.
• Coach arrivals and departures: where they stop and how many at a time.
• Sound and time restrictions on terraces.

Contracting the room block: what to look for

• Cut-off date: when unallocated rooms are released.
• Attrition: what percentage of the block you can reduce without penalty, and until when.
• Cancellation: the scale of penalties by date.
• Minimum occupancy linked to the meeting room rate or the DDR.
• Rates for nights before and after the event.
• Tourist tax: in Barcelona, from 1 April 2026, €12 per person per night in 5-star hotels and €8.40 in 4-star hotels, up to a maximum of seven nights, according to Law 2/2026 and the municipal surcharge. We explain it in tourist tax for groups.
• Trade show weeks: if your date coincides with MWC, ISE or another major trade show, the terms change. See the 2027 calendar.
