I had the opportunity to stay more than a month in Maite's place and my experience there was more than perfect: I had a great bedroom. More importantly is that she is a nice host with whom I could enjoy nice conversations and excellent meal (because she is a cook :) ). Maite is a very friendly lady! She made all her efforts to help with anything I needed both at her apartment and also in Madrid. The location was super well communicated with the entire city of Madrid, there is a supermarket just downstairs, couple of bars and restaurants nearby.
I would definitely recommend anyone who would like to stay in Madrid to be at her place if it is available.
