Spacious apartment suitable for a longer stay. Negative points: there is no visible staff in the hotel. Communication about how to enter the hotel and room was sent from an email I did not recognize that invited to click on a link. No communication through the Hotels app. I was never given a transport card (in Geneva hotel guests get free public transportation ) adding extra cost to my stay. E-mails remained unanswered. The room was never cleaned during my stay.

"The cleanliness, staff, location were all excellent! A great choice for an overnight stay near the airport and train stations. We could have used a couple of extra pillows, and the "night-stands (trays) on the walls between the beds were so tiny--there was almost no place to place any personal items ..."
