Juan was waiting for me at the flat at the appointed time. I was able to message via the wifi on the airport express bus to let him know my flight had landed on time. The location is an easy 10-minute walk from the Cibeles stop. The view of the Vazquez de Mella square from the flat is gorgeous. The flat faces east, which provides beautiful light throughout the day. There are black-out screens to help sleep late if needed. Everything you might require is provided in the cozy flat, and the bed is quite comfortable. There is quite a bit of closet space, the decorations are very tasteful and functional, and the cleaning is immaculate. It was such a pleasure to have a full apartment to come home to after a day of sightseeing in this beautiful city. The location is a couple blocks from the best shopping (Gran Via and Fuencarral) and surrounded by literally hundreds of restaurants and bars. I stayed Sunday-Tuesday nights, so the street commotion was rather muted. I imagine it is livelier on the weekends, but the excellent windows provide very good soundproofing. Besides, if you are looking for a quiet holiday, perhaps a stay in the country is a better option :) Be sure to go to the rooftop deck of the Hotel Oscar across the plaza for a cocktail -- a bit pricey, but killer views and atmosphere. When I come back to Madrid (which will be soon), I will absolutely contact Juan first to see if I can stay again.
