This is a nice, old apartment convenient to public transportation and just a 15 minute walk from Lake Geneva. We liked the location and the check-in was very smooth. The kitchen was also well equipped.
We stayed during a heatwave and the apartment just isn't great for hot weather. Two of the bedrooms do not have real windows, but instead small skylights that can only prop open a few centimeters. We were not able to see this in the pictures. These rooms were not equipped with fans to help with air circulation during our visit. This meant it was difficult to cool them down enough for our kid to sleep well. The apartment is on the top floor of a building, so cooling it down is likely always difficult.
We do not recommend the apartment in the summer months, but would likely enjoy staying here other times of the year.
