Good studio apartment in an excellent location that is perfect for sightseeing in Madrid. The apartment had all the necessities and was like a decent sized hotel room—big enough for a solo traveler or a couple. All the appliances worked and Wifi worked well. Nothing extra, though (i.e., need to buy even the most basic condiments for the kitchen, no travel guide in the apartment). Host responded promptly to my questions. As some others have noted, the walls are thin. It’s a busy area so street noise could also be an issue if you’re sensitive to that.
