David is a very nice guy, he is willingly talk to you and give any informations you need. And the house is just perfect, very modern, very good decorated,very cozy and clean. Besides he provides toast and coffee in the morning, just make you feel at home. There is metro station very close to the house, so it is very convenient to go anywhere.
It is one of the best house that I have experienced in airbnb. If you play in madrid, I'll definitely recommend it.
