This is an excellent room if you are looking for a place to sleep in a very central location. The room is small but clean, Lina Maria is an excellent, friendly host, and everything is as advertised.
This room might not be for you if you are looking for a lot of space, or need to sleep at low temperatures (although there's a fan, buildings can get quite warm in Barcelona in summer; that's life, I guess). But if you want to arrive at the station and ten minutes later be settled in, like me, this is perfect.
