As described, this flat is what it needs to relax for a few days in Madrid. Fits for a single person or a couple. Located in the middle of three metro lines, after a 10 to 15mn you can reach any part of the city.
Facilities like Pharmacy and Grocery Store are in the corner. Located outside the center, in a peaceful and calm neighborhood you won't be distrurbed in the night.
Communication went super well with Eduardo.
