HIGHLY recommend you stay at Oasi when visiting Caye Caulker. It was clean, quiet and peaceful, and Luciana was always readily available to help and answer any question.
She had a taxi waiting for us at the ferry, greeted us at her lovely establishment when we arrived, showed us the grounds, our room, the pool, bar and restaurant, and set aside two bicycles for our use.
Oasi is far enough away from the hustle and bustle of the village that you can enjoy peace and quiet but close enough to walk, bike or taxi to the village or the split in minutes as well.
Great place and great location with an AMAZING host.
