We had single rooms. They are small, as others have said, but fine for a short stay. The rooms could do with an update, but they were clean and comfortable. We had rooms at the back so they were quiet too.
Staff were friendly and helpful. We decided to have the breakfasts as there was a good range of options - fresh fruit, yogurts, cereals, cold spread (cheese, pate, meats) as well as a hot option (eggs, sausage etc) as well as good bread & croissants/pain chocolat with wide choice of teas, coffee, juice.
Only issue was the rooms were quite hot and we couldnt figure out how we could turn the heating down, so had to open the windows - not a great solution given how important it is these days not to waste energy!
