Ruben was a great host: he gave me a tour of the neighborhood, recommended good places to eat, quick to respond to messages, and he even offered to help with spanish paperwork.
The house has all you need to cook, wash your clothes etc., and is very clean.
Be aware that the room is interior, a concept you may not be familiar with if you have never been to Barcelona. That is, the room's window is on a lightwell.
Recommended for short stays.
