Good hotel, well located from center, restaurants, metro, main station. Very clean, great staff. Breakfast a bit light for the price, but that's Switzerland. Street is quite noisy but windows are well sound proof.
I had a double room, then the appartement which is great, a lot of place, small kitchen. Weather was warm, so you have air conditioning system in the room, but you have to put the evacuation by the windows, and thus, keep it open. Not really practical, eco-saver and functional.
