Excellent place to stay.
It is walking distance of most important places. Beds were comfortable and the place at night was very quiet, wich is important when you need to recover for another "walking therapy" next day . It has all the appliances you need, we didn't use 'cause we spent most of the time outside.
Anabel, is a wonderful person, she is always willing to help. The airport was extremely busy ( a lot of flights landed a same time) and it cause a couple hours delay to arrive at the apartment, and she waited for us.
Definitely, next trip to Madrid, I will try to stay here again.
GRACIAS Anabel !!!!!
