We had a very good stay at Marta's apartment. The flat is on Carrer de Sants, a street full of shops, restaurants, supermarkets, bars, bakeries etc but is also strategic, very close to plaza de espana and literaly with a metro station in front of the main door (but many useful buses also pass by the street). The flat is intimate and comfy, equipped with everything. Marta is very nice and gives you a lot of useful tips. Totally recommended!
