Ana's flat is just perfect. The location is fantastic (2 minutes away from Plaza Mayor). It is very nicely decorated. The beds are extremely comfortable and the flat is very quiet (although located in a very lively area) thanks to very efficient double-glass windows. It was perfectly clean when we arrived and the heating system was very efficient. Ana has also been extremely helpful and we enjoyed her warm welcome a lot. We will definitely come back to her place the next time we will go to Madrid.
