This apartment is in a generally quiet building in an excellent location, very close to all the major museums and by a lot of restaurants. It is just a few blocks away from a metro station and major streets in central Madrid (Calle Atocha). This is a clean and nice apartment with a well-stocked kitchen/laundry and a good sized dining table and bedrooms. Ana was helpful with the checkin and checkout.
While we were there there were renovations happening in the building, mostly painting of external walls, with sounds of ladders and workers most days during the day. But they wrapped up by about 6pm most days.
Overall, a great place to stay.
