Very good apartment if you decide to visit Madrid. There is everything necessary for your stay - just as described. The location is very central - just 5 minutes walk from Puerta del Sol. The only thing not very nice are many immigrants in the area (around Lavapies), but we didn't have any problems (but we came back to the apartment at the latest 23 o'clock).
The apartments is very clean and maintained. Carlos (the host) is very friendly and will answer everything you ask him (we talked to him in English, which is almost impossible in Spain).

It was perfect, I recommend it to everybody
