Very centrally located! Maria is very responsive and provides LOTS of local tips for places to eat, places to see, etc. The hot water and heat worked great (important because it was chilly when we stayed in Madrid!) and she has a full kitchen that we used to make dinner a few nights. I also appreciated that she had a hairdryer :) No WiFi, but we knew that, and we were able to connect to WiFi at the local market close by. Overall great value!
