Me and my friend stayed in Vintage Nest for 4 nights. The flat was exactly as shown on the pictures and it was very clean. The bedroom is nice and quiet, since it's facing the backyard. And the bed was so comfortable that I had troubles sleeping in my own bed after returning back home!
Getting and returning the keys went well, because both Mariano and his friend Ruben have keys to the flat.
Overall it was a very good first AirBnB experience!! :)
