Our stay in Mariana's place was great. My friend and I had an excellent time. The location is perfect. You can go to the main spots that madrid has to offer by foot if you choose to. And the metro is a few steps from the apartment if you prefer to go around the city that way. The apartment was really clean and we didn't have any problems with outside noises. The place is small but we never felt unconfortable and it covered all we were looking for, a place with great location and a simple but well equiped kitchen so we could prepare some of our meals. Mind that the bathroom is a little small, my friend and I didn't bother us but maybe a person with a bigger constitution might. Sadly we didn't get to meet with Mariana, but she never stoped answering our messages. We did meet with her brother Andrés, he was responsable for given us the keys, show us the place around and tell us the house rules. He was really kind even though we were late (it was hard for us to find our way trought the metro sistem when we arrived). He even took his time to give us good advises how to get around the city. Over all it was a fantastic experience I would definitely stay in Mariana's place again.
