Location, location, location! At the intersection of Rambla de Catalunya and Carrer de Valencía, a couple minutes' walk away from the Passeig de Garcia train station, surrounded by shopping and restaurants (you've got to do Cerverseria Catalana), this apartment is absolutely fantastic. It sleeps 10, across 5 bedrooms, with a full, large kitchen and a living/dining room flooded with light.
If you have a chance, stay here. You won't regret it.
