We greatly enjoyed our stay. It is convenient to the airport about 25 minutes (30 euros) fixed price. Walking distance to metro from which you can get to any part of Madrid in about half an hour. The railway station is also located there so short trips outside Madrid are also convenient.
There is a grocery store, Mercadona just next to the apartment building which is great because it carries all groceries that you need for a short stay. Cafes and restaurants are within walking distance.
Apartment is modern and has all amenities. Only downside is the work being done in the roof, it is little off putting to see the exposed ceiling with wires etc. Once it is completed, it will be great. However, it did not bother us.
