I had a good stay in Alvaros room. Communication was brilliant. Sadly Alvaro can't speak English so I didn't spend a lot of time with him.
The flat is really quite, sometimes throughout the day you hear little noise from the street (there's a bistro under the window) or from elsewhere in the house.
Water for showering needs a while to heat up.
Location is good despite it's a little far from the centre, but you have different bus lines 1-7 min away which take you there in 15-20 min. But in the night, after 10-12pm, you have to look how to get home as the busses move rare.
Recommendation!
