we had a lovely time in Barcelona and loved the place we stayed in. Pere was very nice and welcoming. he was available to all our questions.
the neighborhood is fantastic! lots of cafes and restaurants. there is a nice market nearby. the metro is a 5 minutes walk from the apartment and only about 10 minute to Catalonia square.
the apartment is very well maintained, it has everything you can think of for your vacation (including things for your first breakfast). very recommended.
