We stayed at Tsvetana's house for 4 days. The room is not very big, maybe small for two people, but for the price it is very cheap. The site is far from the center, but well linked to it. In fact, metro can be reached in 3 minute by walking. The neighbourhood, well, seems to be not safe in late night. Anyway there are some shops near the house, also a little bazar. Tsvetana has been very kind, helping us with all information about how to use kitchen. If I would come back in Madrid, I'll consider the idea to book here.
