9.6/10 Exceptional! (144 reviews)
This apartment/hotel is as SUCH. Great find! We are a family of 5 - 2 adults 3 teenagers. Plenty of room! My son had a large bed in the living room (pull out sofa) then my girls had a large bed with en-suite bathroom. His ad and I had large bed with en-suite bathroom. But another bathroom in the hallway. They kept the fridge stocked with waters and apple juice and soda. Apartment also had a full kitchen- we bought breakfast food at the Coop down the street. Convenient location! Best part is they offer free laundry. We have them 2 big baskets of dirty laundry from our trip to Paris and it was returned at 3pm washed and dried and folded! Allowed us to bring half of what we would have needed to bring. Also had a private parking spot for an extra 35 chf per day. The staff is SO nice. 5 stars!

"A nice hotel in the centre of Geneva. It is right on the edge of the Old City, so a short walk up the hill gets you to many interesting restaurants. In the other direction it is a five minute walk to the promenade on the lake."
