This is a self-contained "studio apartment" in the most central part of Madrid. For the price and location, it is a very good option. The space is definitely small but it has its own kitchen and bathroom, as well as a desk for working. The light from the lightwell in the middle of the building brightens the space too. This is definitely cozy -- perfect for a solo traveler. The host, Javier, is friendly, helpful, and easy to reach. You're at the back of a long flat that has other rented rooms, but you are off to yourself, behind your own locked door and with your bathroom inside, so the rest of the flat is just what you see entering and exiting. While the room is definitely tucked back toward the back of the building, the upside is you hear absolutely none of the noise that you'd hear if you were facing the busy street.
