My girlfriend and I stayed here for three nights and, from the moment we first enquired, both Hilary and Pike could not have been more helpful.
Hilary provided us with a very thorough description of how best to get to them from Hopkins in the south of Belize, and Pike was very kind to pick us up from and drive us back to the nearby water taxi terminal. Everywhere on the island is only a short walk or an even shorter bike ride away from their place.
The apartment is spacious, well furnished and very clean, and there's a hob and pans if you want to cook. There are also lots of great restaurants very nearby which serve amazing fresh seafood caught locally. I would also highly recommend doing a boat trip during your stay - reasonably priced and we swam with turtles and sharks - and our hosts were great in helping us choose the best company to go with.
If you've yet to visit Belize, it's incredible, and this is a perfect place to stay in Caye Caulker.
