It's basically a room with a bathroom on a first floor in a house. The best is the location and the price, just a 5 min walk from door 10 of T1. My flight was delayed 6 1/2 hours and landed at 2:00 am, so it was a little bit scary to walk to the house at that hour but Irma was constantly in touch with me, so she quickly opened the door when I rang the bell.
I just stayed for 12 hours and flew next day, but she let me store my luggage in the room for the time needed.
