Charo is a nice host, after our arrival, Charo explained every thing (including check-in/out, how to use equipment, and information for tourists, etc) patiently and clearly. The room was clean and tidy. It was unbelievable quite and locate right in the city center. The only thing that we were little bit worried was that our bedroom cannot be locked while we were sleeping, anyway the entrance of the whole flat was proper locked so everything was all right. I slept tight and had a good time in Madrid :)
