Chila herself is a great, great hostess, not to be missed. I want to be clear that when I selected "she met my expectations" it was only because she has a high bar for hospitality rated highly by others, so I knew she was not to be missed for a great stay at Caye Caulker :-). Definitely take advantage of the free kayaks, we only did for one day and probably should have done it again (but we were busy with other stuff like snorkeling and scuba diving).
The suite was great, it has a really nice breeze that goes through the room when you open the doors (balcony and entrance) and allow the screen doors to have the wind pass through. It's quiet at night when you close the doors, and the AC will drown out any noise that may be going outside (but things got quiet typically around 9-9:30pm). We stayed for a week and one of our days we spent about the entire day sitting on the balcony and watching the ocean and people walking under us.
It's a pretty good location, just beyond the street sellers, next to two scuba shops, and not far from the split.
