Bottom-line: this apartment looks just as pictured, is clean, and the location is spectacular to walk to many places in central Madrid or catch the metro. On a busy day the street noise is noticeable but was not so bad for my girlfriend and I.
Our hosts were wonderful in accepting the reservation right away (only waited 1 hour) as we had an issue with our previous plans + they responded to questions and messages very quickly and in a friendly way. The kitchen has everything you need, the washing machine works perfectly.
