Great stay in Barcelona for me and my girlfriend. Samuel is very nice and absolutely helpful. Our flight was scheduled very late in the evening and Samuel waited for us until 1 a.m. The apartment is located near the Saint Antoni metro station and only 10 min walking from the Mercado de La Boqueria and La Rambla. The district is full of restaurants and pubs, which are open also late in the night.
The room was clean, but a bit small with no so much space for the luggages and there is no possibility to lock the door. I suggest it for a weekend, not for a long stay.
