Terrific place in a great location. Short walk from train station. Even shorter walk from Artes subway stop. We went to Madrid for museums. Reina Sofia (with Picasso’s Guernica) is across the street. Prado is a pleasant walk on a nice day. Thyssen, best of the three, is either a long walk or a short taxi ride.
Apartment is ground floor, although three steps up and then three down. Modern appliances. Two bedrooms couldn’t be much smaller, but if your travel companion is not your sleeping companion, you’re both behind closed doors. Windows on a courtyard, so not much light, but appreciate that in the morning. Lots of grocery stores and eating places in the neighborhood, some with carry-out. WiFi works well. Friendly, informative host (we understood each other’s Spanish). I could have stayed another five days.
