Beautiful, well appointed and well located flat in central Geneva, with a supermarket right outside. Very handy for the UN, and an easy walk to the main station and the airport. Great view out over the mountains.
Downsides? We were there in midwinter, and the radiators didn't seem too powerful, but that wouldn't be an issue at other times. And a few little niggles - dishwasher didn't work and no shampoo as per listing.
Also, all the sockets are the hexagonal Swiss ones, so if you only have circular plugs, you'll need adaptors.
