Good value for money, room very small but clean and nice bed. Location is further downhill and away from Madrid center than shown when booking, only a few hundred meters but makes a difference due to the hills. Common area is tiny/non existent and is not a place you would want to cook and eat. On final day, was told by host could only use the air conditioning fan in room at 8am, despite the boiling temperatures of the city in the summer.
For the price, would recommend to a solo traveller who enjoys living in a cultural area near the center
