We loved our stay here! We found the apartment easily and there was quick and clear communication from the host to help us with transportation options. Everything was spotless when we arrived and there was someone waiting for us to explain the basics of the apartment. The main door on the ground floor was a little difficult to open, but we got the hang of it! This area of Madrid is definitely a bit livelier and noisier, so I would recommend bringing earplugs if you are a light sleeper and have the windows open at night to keep cool. The living room and bedroom are open, so there is not as much privacy, but this wasn't an issue for us. The single beds are bunkbeds in one room, which was fine for us but may not be easy for people with mobility difficulties. This apartment packs a lot in terms of making a smaller space feel very open and spacious.
On the same block there is a place for a typical Spanish lunch for ten euros. There are some nice shops a few blocks away with typical alpargatas shoes and other things that are not just stopping at El Corte Inglés to shop.
There is a grocery store about a 1.5 blocks away which helped us get what we needed to make breakfast at the apartment before heading out for the day.
I would definitely recommend this place to friends.
