Ivaylo has a very clean and accurate flat (not so common in Spain - rooms are often not so clean). He is a very friendlt person and I would recommend everyone to stay at his place. Just a note for travellers: bring cold clothes if you are travelling in winter or spring. There is no central heating in a lot of flats in Madrid. That could be a real problem because it is too cold inside. In any other aspects, totally recommendable! Thanks, Ivo!
