We had a wonderful stay at Elise’s apartment. The apartment was clean. They accommodated our early check-in request. The location was very convenient for walking. You are 10 minutes walk to the museums, Atocha train station, la Latina and even closer to El Rastro. The Lavapies neighborhood is lively. Around the corner from a stocked 24 hour supermarket. Tons of international restaurants and bars. The Mercado San Fernando was a vibrant Mecca for young madrilenos. (A three minute walk).As for the apartment, it is on the 4th floor, so lots of walking upstairs. You do need to be careful not to bang your head especially in the bedroom as there are slanted ceilings and wooden and steel beams. But if you’re careful, you’ll get a great sleep on a very comfortable bed facing the quiet side of the street. Elise left a very helpful book of recommendations. Communication was great. I’d definitely recommend staying in this apartment
