Great place to stay, a short walk from Gare Cornavin at a reasonable price. Deborah and Mark were excellent, friendly and exceptionally accomodating hosts. Their cat is also wonderfully (borderline miraculously) well-behaved.
The room itself can get somewhat stuffy, but it's easily handled by cracking open the window and using the fan provided. The patio provides also provides a nice escape in the evening if you need to allow the room to cool a little before turning in.
