The appartment is very clean and has everything you need! In a quiet street, but very central. The area is nice and you can go everywhere around by walk.
Mariano is very friendly and he gave us useful tips (good restaurants near by, bars, things to do and to see in Madrid...).
Mariano was out of town during our weekend so Beth welcomed us. She is a very nice and friendly woman, and available in case of any problem.
Muchas gracias!
