Joaquin and his wife has been amazing in terms of hospitality. They kept the place very clean and made sure I was very comfortable. They have always been respondent and encourage me to ask whether I needed something. The whole apartment was furnished and new, and I enjoyed my living in the room.
On top of that, the location is absolutely great, right close to Plaça Españya, easy to commute. Best place in the city to stay for Mobile World Congress (if you are going).
