The apartment is in a good location and is convenient to the train station and the lake. While the condition of the furnishings and flooring is a bit worn-out, the apartment was clean and functional (except for the air conditioning).
I was in Geneva to attend a conference during three very warm days in May. While the communication with the owner was very good with regard to the booking and the check-in, they neglected to mention that the air conditioning wasn't working. Apparently it was broken in the whole building. This resulted in trying to keep the room cool with a portable fan and leaving the windows open. It was very loud from the street noise and too hot for comfortable sleeping.
Had the owner let me know the the air conditioning wasn't working, I would have booked somewhere else for my stay. By the time I found out (when I tried to switch on the air conditioning) it was too late to find alternative accommodations.
