Apartment is clean, bright and comfort for a short stay. The main tourist atractions within walking distance. All describtion of apartment is totally corresponds to reality. Edu is very responsible host.
From disadvantages - we were in winter and apartment is cold, there is no heating system and air-conditions do not help. But while searching accomodation I understood that this is a problem of major part of private flats in Madrid, especially in downtown. Also sometimes there were a little smell of sewerage from a shower.
Anyway I recommend this apartment and host!
