This is an excellent apartment. Spacious, with three bedrooms, each with a double bed. The kitchen is stocked with the things you need to eat and cook. It is located within walking distance of most things you would want to see (Poble Sec, Plaza Espanya, Ramblas, Plaza Catalunya, Universitat, Passeig de Gracia, Gothic Quarter, Raval, Bonn, etc.). All of those things are 10-25 mins away. There are also lots of places to eat in the neighborhood, including vegetarian friendly places, and a great bread shop call 'Turris'. All in all, for all the things that were important to us (location, number of bedrooms, space, price), we could not have found a better apartment.
Also note: the apartment is located on the first floor, so it is close to the street. The two downsides to the apartment are that you will hear the traffic when you open the sliding door to the balcony and that it can be hot inside in the summer time (but this is common in Barcelona since AC is uncommon). We stayed here for 6 weeks in the hottest part of the year so we bought two fans from nearby shops.
