This place is amazing. Elsa greeted us and reviewed the apartment information and told us to contact her if we had any questions. We had one tiny problem getting the door to unlock one time (it ended up being very comical) but had no problems after that and we learned the lock system is different than what we're used to. The location is exactly what my friend and I wanted - close to the market, authentic neighborhood restaurants and a few bars (I highly recommend El Viajero for good drinks, food and terrace views/great atmosphere). We pretty much walked everywhere! The apartment location is very safe, which is always a concern for two females traveling as we were. The whole trip was exactly what we wanted and Elsa's place helped us truly experience all that Madrid has to offer!
