I spent 3 days in Ravier's duplex with my brother and cousin and the description was exact. The apartment is located in a lively and quite safe area from where you reach every monument or museum on foot so it is ideal to visit Madrid.
Ravier is a nice host, he welcomed us although it was a working day for him and he took the time to fix a problem with the Wifi that perfectly worked after that. The only negative point I have to do is about the cleaning which could be better especially the blanket on the large bed and in the bathroom.
