I like Hotel Confortel for both its service and location. Researching establishments near the center of the city is one good way to choose a hotel in Barcelona, but this hotel is near the beach and that could be an even better incentive depending on the season. It’s also only four subway stops from Plaça Catalunya, putting you in the center quite quickly. Icing on the cake? They have a wonderful pool, and all kids under 12 can stay for free.
