If you need to stay close to Geneva and you have a car, you must stay there.
If you like the "Fawlty Towers" serie, you will just LOVE this small hotel. I want to precise that the owners has nothing in common with Sybil and Basil : they are charming, welcoming, caring and very professionnal.
The hotel is located in their wonderful old family house, decorated in a british style.
A part the rooms (fresh flowers, nice, comfortable, clean, just old fashion enough, some with a balcony and stunning view on the country side), you have access to a breakfast dining room (breakfast just perfect) a bar-salon and a conservatory very nicely decorated with the family antics. The house is surrounded by a park, with tennis court. The only downside is the highway that you can hear a little bit in the background, when you are in the park or on the balcony. Except that everything is just so homely and charming. An other way to experience Switzerland.
Why I stay there : I was getting married and I needed accommodation for him & I and our friends (my home was completely invaded by my charming italian family future in law).
