Fasthotel in Anncey is a great solution if you only want to stay a short time. We only spent one night there on our way to the Alps, and the place offered everything we needed, mainly a comfortable bed and a clean room and bathroom. Breakfast is offered as well, it's a very simple buffet, but again, all you need to get you going in the morning. Very nice coffee!! :-)
The room we stayed in was very small, you don't have much space to store any luggage, so really not suitable if you are travelling with more than one suitcase. But again, there's not a lot more you need. There was a TV, very good WiFi, hot shower, and everything was very clean and comfortable.
Don't expect a 5* hotel and you will not be disappointed!
