The hosts are responsive and gave clear instructions on the check-in and check-out process. We were allowed to check in over an hour early after arriving at the train station, which was great! The hosts left a detailed map of central Madrid and had several neighborhood restaurant/bar recommendations that turned out to be amazing (our favorites were Casa Gonzales for wine/meats/cheeses & Restaurante TriCiclo - incredible sit-down dinner...just make a reservation and go, you won’t regret it). The location is great being a 5-20 min walk from just about every main attraction in central Madrid including the Chueca & Salamanca neighborhoods. Getting to the apartment requires climbing a few flights of stairs (not a problem for us). The apartment was smaller than expected, especially the bathroom, but was comfortable enough for our short stay.
