Fernando's place is great! : centrally located and walkable, just a couple of blocks from more than one metro station, makes for an easy commute to and from the airport and any part of Madrid.
There are plenty of restaurants, cafes and supermarkets within walking distance as well.
We had to change the time of our arrival at the last minute, and Fernando and Renata were very flexible and accommodating.
The apartment is comfortable, and has everything you might need for your stay, including washer and even some cooking basics!
Fernando was very responsive and sent specific responses shortly after any questions/doubts that we had.
All in all we had a great stay, and have already recommended Fernando to family and friends!
