I stayed at the property for three nights in January 2017. I found it to be as advertised: clean and comfortable. There are no valves on the radiators with which to control the heat -- which was very adequate. If it got too hot, I simply opened the window.
The walls are bare, giving the property a very stark and spartan quality. It didn't really affect my overall experience on way or the other, but it would be much cozier if somethings were added to the wall decor.
The property is really centrally located. It's a very short walk to downtown and public transport. I will stay again if/when I return to Geneva.
