The flat is as fantastic as in the pictures. There is everything you need, even more. It is beautifully decorated, and the location is more than perfect as Cava Baja is an important street of the city.
Irène and Luis are two lovely people that will give you any advice you need about the city and will make themselves available for any need.
We spent a wonderful time in Madrid and this Airbnb experience is definitively part of it. We highly recommend it and see no other place for us to stay in Madrid next time but this one.
