We went by car from Poland to the conference which was held partly in Grenoble and partly at Villard de Lans - 40km away . The hotel is located in Moirans which is about 10km from Grenoble borders, so if you traveling by car you have to count in a hudge traffic :)
But, despite of this the location is pretty ok, it is close the main street, but far enough not to hear the cars passing by. It is dog friendly and has a big garden outside. The staff is friendly and ready to help.
Rooms are not very big, but each one has it own air conditioning and heating so you can set the temperature to your needs. The equipment is rather old but it is not dirty.
Parking is free of charge and there is an in-room Wi-Fi but it works very, very slow..
Hotel has it's own restaurant and serves breakfasts. In the evening it is open only from 7pm till 10pm (like most of restaurants there..).
Over all comparing price to conditions it is really OK.
