My husband and I stayed 5 nights.
The apartment was simple and clean with all the amenities needed for an extended stay.
Good quiet air conditioning, queen sized bed, ample storage, solid hot water, shower only in our ground floor apartment. The internet connectivity was good enough to stream a Netflix movie. There are two small flat screen TV's with a decent cable package.
The building is two short blocks from the beach. There is a supermarket down the block along with a few bars and restaurants.
The main part of San Pedro town is a solid 15 minute walk which can be done on the busy Main Street or along the quiet beach.
Lisa the care taker, was always available for local advice.
If you want to see more of Ambergris Cay a golf cart or bikes can be rented from the building at a competitive rate.
This place is a good value for the budget conscious travelers.
