Diego's place is super cozy and in a great location! The room is small but has all you could need.
In summer this place is awesome thanks to the constant air current running through the apartment if you open the windows. However, in winter it might get fairly cold, especially since the windows don't insulate particularly well, so a small space heater is a must.
Diego himself is incredibly friendly and helpful, very clean, and super respectful of everyone's space and privacy.
I highly recommend staying with Diego if you have the opportunity!
