This room is in a strategic position, a 20-minute walk from Porte Maillot (Beauvais airport shuttle arrival) and a few minutes from the arc de triomphe and various accesses to the metro. It is very very small, fine for one person alone, but there's everything you need. The toilet is outside the door, but it's private and clean.
The host is very kind, she welcomed me personally and has always been very quick and efficient in communications. I recommend it!
