Travelers ❤️ these 🏨 after their flight to Castries

Bel Jou Hotel – Adults Only – All Inclusive
Service is outstanding and everyone is so friendly. Rooms are musty, need better cleaning products or more airing out. Beds too soft. Views are great. Sounds really carries.ie not really sound proof. Can hear entertainment at night which is not a bad thing as music is really good.

Superb place to stay well priced superb friendly staff especially the supervisor she will go out the way for the guest that stay here, restaurant on site serving breakfast and lunch only. Shop around the corner across the road from Castries Airport and not far from the Ferry Port… 💯 I would stay ...

All of the staff, food, amenities and other activities were amazing. The only issue we had was taxi’s being late, otherwise very easy to schedule everything through concierge.
