We had a wonderful time at Ana's place. She is very kind and helpful, a true host. The location was absolutely perfect, right next to Retiro (Madrid's flagship, breathtaking park). We walked through the park every day going to and from the city (a 25-30 min walk to Plaza Mayor, Sol), quite enjoyable way to start and finish the day. If you enjoy running, the park is excellent for a morning jog.
The apartment is big enough for a family of 5, we had a 2 month old baby and we had no issues at all -thanks to elevators. There are tons of books (in spanish), so my family enjoyed unwinding while reading each day. We would definitely come back to Ana's place.
