Crissi is a wonderful host, lively and has two lovely cats that are so friendly that you will quickly find yourself at home.
The living room (sleeping area) is huge, and you have everything you need for your stay, and you'll have all the privacy you need.
Crissi was very helpful and answered quickly even late.
The flat is close to multiple Metro lines, and it is easy and fast to join the Madrid centre.
Highly recommended!
