Very friendly and great host. Pointed out several fine locations to eat and enjoy the local culture.
The terrace is a wonderful spot for breakfast I. The morning. The apartment is perfect for a solo traveler or two people but could accommodate 4 if need be.
The location is close to EVERYTHING. I was able to walk to all the museums, The parks, all the major plazas.
The kitchen is very small so be ready for that. But, it's Madrid, so eat breakfast at the flat and then go enjoy the restaurants of the city. It's very easy from here.
