We had a really nice stay at Pere's. We were 5 people, used the appartment as our base for exploring the city. It is really close to the metro and some buses. And for the days that you want to return late, there are also nice areas nearby (either for shopping, drinking / eating, and nightclubs). Although we didn't meet Pere, he had arranged everything for us (we arrived late at night and left early in the morning without problems), and there was even coffee and some food for breakfast :). Overall we really enjoyed our stay.
