Isidre's place is great for a trip to Barcelona. It is in a quieter spot of the city, with mostly families living in the building, but that doesn't stop you from seeing the city. A four minute walk will get you to the Tarragona line 3 metro and that can take you pretty much anywhere in Barcelona. Even without the metro, you can walk to restaurants and sights in 20-30 minutes (which is nothing and which I recommend so you get a feel for the city). Clean, comfortable beds, all necessary amenities; I would stay there again and would definitely recommend.
