Fernando is a very kind and attentionate person. He has a lot to tell and teach and will do anything to make you feel home and have a nice visit time.
The appartment is in the basement so a little bit humid in the bedroom but cozy and practical. Very silent in the night which is a big plus in Madrid, not mentioning the location which is quite perfect.
And comfortable matresses (hard enough).
A little warning though: you'd better speak spanish^^
