Javier's loft is very modern, beautiful and clean. It is very comfortable and you can sleep really well because it is quiet and you can make it as dark as you want. Also, we stayed during the summer, which is really hot in Madrid, and we picked his place because it has A/C. We didn't expect to have 2 splits A/C, which was really convenient.
Kitchen is beautiful and comfortable. If you like to buy a lot of food, refrigerator is bigger compared to traditional European small places.
Everything was spotless and new.
It is not close to downtown, but there is a metro station very close by.
