Charo and her family are very friendly and explained all the highlights in Madrid we had to see. Especially the sunset location was very nice!
The room itself was clean and provided sufficient space. Bed was a bit short (I estimate it to be 1.90m x 1.40m), but as the matress lays on top of the bed, my feet could protrude comfortable without problems.
Also the flexibility to drop the lugage already in the morning on the day of arrival and to leave the luggage till departure in the evening was very kind.
The breakfast was basic and contained a local speciality. Good enough to start your day!
The location is also very nice and allows you to explore most highlights easily by foot or metro.
All in all, this was an excellent choice for the price we paid (around 70 euros in total for Friday and Saturday night (plus 10 for airbnb) in September). I would really recommend it.
