I am from Madrid but live now abroad and chose this location because it's no doubt one of the best locations to visit the city. Everything (bars, restaurants, cool shops, tourist and cultural attractions, etc.) is located within walking distance and it's also close to several subway stations. The communication with the host was very friendly and she always replied very fast to any message. I received clear instructions for the check-in (contactless) and was easy to enter the apartment. The apartment is located on a second floor without elevator, but unles you have real movility problems, that shouldn't be a problem. I chose an interior apartment since I know how loud Madrid can get to be and it was really quiet, which was exactly what I was looking for. The only downside is that it's a little bit dark, but at the end, once you are in Madrid, you're not going to be too much inside anyway and you will appreciate being able to sleep at night without noise! The apartment has a spacious bedroom with a very confortable bed, a kitchen, a living room and a bathroom and is fully equiped with anything you may need for a short stay (including wasching machine and air condition/heating). Everything was really clean and the bathroom was very modern with good ligthing and high preasure shower.
I can only recommend to stay here!
Gracias Celina ;)
