As first-timers to Belize, we really didn't know what to expect, but Luis (the true MVP of this experience) was on the ball ahead of time, knew exactly when we'd be checking in, and was 100% reachable during our entire time there.
The accommodations were an amazing value for the money: a full kitchen, utensils and a few dishes supplied, a full-size fridge, nice seating area, a TV with dozens of channels, a separate, spacious bedroom with a nice full bath. And it was all neat, clean, and looks new.
There's quite a bit to see (and eat) on foot nearby, even within a block or two, and while a golf cart might help with further exploration, you can certainly get by without one.
In short: along a main thoroughfare, clean, well-appointed, excellent value, Luis is super-responsive and helpful with recommendations on the area.
