Our stay at Sergi's was great! We felt very welcome as the first Airbnb guest here. Such a hospitality. The metro stop La Pau is really convenient, indeed only 5 stops from Segrada Familia(10-15 min). But you can take the L2 or L4 to a lot of places in Barcelona. The apartment has everything you need. De bathroom is a bit small, but the shower is nice and warm. You don't have that everywhere in Barcelona. Ask Sergi for some suggestions for lunch or dinner and he will have plenty for you.
