I stayed here for 4 nights and love it since the first night.. this apartment is really a 9.5/10.. the location is perfect, the apartment itself is really newly renovated with modern minimalist theme, bed is very comfy, and the amenities and facitilies are working properly.. Carlos as a host he was explaning and providing essential information that I needed..
If I visit Madrid in the future will definitely contact you again :)
I recommend this apartment.
