Isabel's flat was very nice and cosy. It is small but very charming and we felt very comfortable in it. It has everything you need for two people.
Malasana's area is amazing and the flat is right next to the metro.

We haven't had the chance to meet Isabel but communication was always easy and efficient. Isabel's sister showed us the place and made everything very convenient for us.

I would definitely recommend the place and Isabel as a host!
