We spent 2 nights here in December and had a wonderful time. Aida is a fantastic hostess - she provided us with maps, advice on where to go/ what to see, and even made dinner reservations on our behalf. We stayed in the Saphir room, which was spacious, clean, and well-decorated. The pillows and mattress were very comfortable and the bed linens were beautiful. Breakfast was plentiful and served in Aida's lovely kitchen since it was far too cold to eat outside. I'm sure the outdoor eating area is gorgeous in the summer!
The B&B is situated pretty well - it's a 5-10 min drive from the TGV station and everything in the old center is within walking distance.
