Furnishings and finishes are mostly high end (except strangely the Dining Room table). The beach and sand is gorgeous. Terri, the property manager, couldn't do any better. Derek, the onsite assistant was insanely helpful.
The house lacks a few key details that I have come to expect in an AirBNB - laundry and a dishwasher. The listing doesn't say they have them, I just never checked. Terri will have your laundry done for $10, basically an unlimited amount, which is great and cheap. The front door barely functioned while we were there. The door was suffering from typical salt water exposure. Derek, the onsite guy - it took him two minutes to show me how to lock and unlock it, so it wasn't me. That was supposed to be repaired while we were there but it wasn't.
I wouldn't stay here again though - the house has no curtains and it gets light out at 5:30AM. I would get up and retreat to the living room, but that is all glass and stairs at the sunrise. It made working on a laptop/watching TV/reading very difficult. The pools available next door are extremely small, no shallow section for my 5 year old, and have no shade. The house was not a good fit for a family with young kids. I could see enjoying it more as just a couple. The kitchen/living room are extremely small.
Just some notes if you're considering Ambergris. They have had a multi-year problem with sargasso (sp?). Basically the water was brown 100 yards from shore and 2-4' of seaweed was stacked up on shore the entire time we were there. The good beach is currently on the western side, almost all the houses and lodging are on the eastern side. This has nothing to do with this house as by all appearances it was a problem everywhere on the west side. I just wouldn't expect to snorkel or swim in the water here. Enjoy the views though.
We loved Secret Beach and their beach bars and waterpark and clear water for snorkeling. We spent several days over there. The snorkel trip to Hol Chan was 10/10. Truck Stop was also fantastic for families.
