We really enjoyed our stay at Jose’s apartment: it is just a short walk from a subway station that is close to downtown. The apartment was really clean, and the washing machine was a huge plus for us, as we try to pack lightly, and so we wash our clothes as they get dirty.
As others pointed out, the Puzzle cafe downstairs is very convenient for breakfast or dinner, and modestly priced.
Jose’s advice on areas to visit that he pointed out (actually circled) on a map he gave us and the way he cross referenced it to the subway stations were very helpful as well.
Jose’s apartment is a great place to stay - even for travelers like us, for whom it was our first visit to Barcelona.
