A couple of minor things to note from the hotel description; They do not operate an airport shuttle bus, and there is no car parking on site. However, there is plenty of parking in the vicinity of the hotel. The hotel itself is absolutely perfect as far as I am concerned. It is small enough as to never seem overcrowded, even at full capacity. The rooms are spacious and very clean. Also, the bed was probably the most comfortable I've slept in when away from home. As for the staff, they are attentive and helpful.

Le personnel est à l’écoute, les chambres sont spacieuses et ordonnées. Très belle piscine et spa, petit déjeuner complets et varié. Petit bémol : manque d’équipements dans la salle de sport.
