Esti's flat was a great place for us to stay in Madrid - very central, fully equipped, and easy to find. She was a friendly and welcoming host and left some good restaurant recommendations for us. The flat is quite small but when in Madrid, there are so many things to do in the city that you have everything you need in that space. It also has a great character and was up off the street enough that there was no noise from traffic or people, even though on one of the main city streets. I highly recommend!
