Álvaro's place is in a great location, although on the 5th fland the elevator is rather slow, so be prepared to walk up the stairs occasionally.
Although the place is dedicated for guests while you are booked to stay it's lived in for the rest of the time, so there are a lot of personal items around the apartment which is a little different to normal, but gives the place a genuine charm.
Álvaro was very nice and speaks good English and was happy to give us a few tips on where to get some good street food that was super tasty.
