I had a fantastic time at Claudio's Airbnb in Madrid! He was very polite, helpful and discrete as I stayed in the only bedroom in the flat while he used the sleeping sofa for the duration of my stay. Though the flat is very small this is no problem at all since I was out exploring the city for most of the time and he would work and only come home late. I fully recommend Claudio as a host, especially because of the fantastic location in the heart of Las Letras with bars and restaurants at the doorstep. It should be noted that Claudio sleeps in the living room in close proximity, since this is something that might make people uncomfortable. I had no issues with this whatsoever, but one should be aware of this when booking. My personal experience was not compounded by this at all though, I thoroughly enjoyed my stay.
