The appartement is easy to reach from the airport and not too far away from the city center. Alejandro gives everybody a warm welcome and is always there if you have a question about anything (He is really fast in answering any question and easy to reach if you need help :)).He also has good advices where to eat, drink etc. in Madrid.
The room is not big, but there is a kind of a built-in cupboard to leave the luggage. All in all, I felt at home at Ale's place.
I would definitly recommend his place.
