First and most important to know is that the we are a family of 4 (2 teenagers) and we stayed for 4 weeks (and hope you do too...!!) thus our feedback might be a bit different from others on this list.
Cinnamon is a wonderful host, patient and very supportive. No matter what kind of question we had, she was there for us by mail or WhattsApp with a speedy, honest answer.
If you are planning on staying on the island, make sure you realize that you basically stay in nature. The team on the island (Cpt Reves/Sabo) helps you adjust to it and make smart moves (e.g. close doors and windows because of mosquitoes if the wind dies down which hardly ever happens anyway). The pelicans were our favorite neighbors. The water is crystal clear and ready for a dip. Make sure to check out the night sky - you've never seen anything quite like it!
Talking about the team: We were very well supported during our entire stay. Whenever we had a question about an aspect of the life on the island (e.g. power, fridge, mosquito-coils, waste) we were able to ask Cpt Reves, Sabo or anyone else present. They are patient and will show you everything. We didn't realize that the team would support us on a daily basis (expecting more solitude) , taking us snorkeling, fishing, on excursions (Blue Hole, Half Moon Caye) which they offer at a reasonable price! The snorkeling in the area is some of the best world wide and on top of that this team knows the best ones on Lighthouse Reef! They were also very helpful organising the purchase of the food beforehand (we did the cooking by ourselves) and bringing a huge pot of drinking water every other day free of charge... We enjoyed their company and had memorable moments with them - guys, you're great!
The house itself is very well equipped! Gas stove & oven (lots of pans and oven equipment - we even baked our own bread), a fridge, a wide range of spices, and whatever else you expect from a kitchen/dining room. There is usually some food-stuff left by people (in our case it was pasta, canned vegetables, corn syrup, and more). There is a TV, a wide range of books (I've read 5 while on the island) and even crayons. The WiFi is very limited during the day (if you use up all your data, there is nothing left for the rest of the day - so use it wisely). At night the speed of the WiFi is quite reasonable for everyday stuff like fb, checking news, sending emails however, no youtube or streaming platform worked. The bedrooms are big and the beds are comfortable. We did bring and install our own mosquito nets, which was a good decision; certain nights there were some in the house. The bathroom even has a shower (tip: make sure that there is enough water in the roof-top tank so that you can finish your shower in one go ;-) )
Just around the corner is Itza where you can grab a drink and talk to more people on the island and a bit further on, there is Diving Center Hurracan. It's really your choice how much interaction you are looking for on the island; anything from "just us" to "let's meet everybody" is up to you.
Over-all: we enjoyed this down to earth (or rather sand) stay on the island! We were well supported, and adored the relaxed way of life in this beautiful setting!
We would go back in a heart beat and hope to do so in the future - thank you for everything Cinnamon - Reves - Sabo!
