This is a remarkable little apartment in the middle of a lively pedestrian mall in central Madrid. I've never experienced anything quite like it - almost like staying in a cruise ship compartment. It was sparkling clean, comfortable and well-equipped in every way.
Maria Luisa was a warm, kind, caring and gracious host who met me personally at the door and made a potentially complicated check-in process so easy. She also answered a distress call when I got lost in the middle of the apartment complex. They understand but don't speak much English so be prepared to use a translation app for some communications.
A couple of things to understand about this unique property. It's situated in the middle of a vast apartment block off a pedestrian mall in the heart of Madrid so the street address is not accessible by car and would be hard to find without personal help from the hostess. My cab took me to a location nearby (which I did not expect) and I had to walk about 100 meters to find the actual place with a GPS locator app. Fortunately, Maria Luisa was there to meet me. Not sure how I would have done it without that help. The listing might need to add some more information to orient people coming in by foot with luggage. I have no idea how people do it with a car.
Also, the deep interior location limits the light and the space in the apartment. You need to adjust to that and I would not recommend it to anyone with claustrophobia! :). There is also a fair bit of noise coming through other apartments all around during the day (especially on weekends), so if you are noise sensitive, that can be a challenge. Tenants seem to respect the noise curfew after 11:00 so sleeping was not disturbed but during the day, it can get a bit loud. Again, you need to be comfortable with that level of ambient sound.
Having said that, it's a great value and a super-cool location. The hosts are also wonderful people who are there to support.
