I was attending a conference at the Palexpo and considering the other nearest option was the Starling Hotel at roughly 50-75% higher cost, this hotel was a fantastic option. Breakfast was spare, but functional (hard-boiled eggs, cereal, juice, jelly, croissants), but the restaurant was excellent, with great pizza. Clean rooms, big rooms, great hot water and water pressure. We had a small refrigerator in our room.
There isn't always staff around so if you are used to 24 hour service, this is not your place. Also, it is about 1-2 miles from Geneva city center/waterfront, so for tourists, again, this may not be the best choice. But if you are attending a conference at the Palexpo, this is a great choice.
