My wife and I had a great stay in the guest house. It is a small but comfortable (for 2) updated cottage. Although it sits behind the main house and another beachfront property, it is just a few steps from the beach. We cooked one to two meals per day in the modern kitchen, and we lived on the comfortable porch at night. As you can see in photos, the home grants access to a long dock which gets you out to where the water is 5 feet deep. From the end of the dock you are about 20 yards from the boat channel and 50 yards from amazing snorkeling on the reef!
The house and property were clean and well maintained. We stayed for a week and relied on the transportation the owners provided to and from RTB, which was seamless. There were chairs, a grill, large cooler, snorkels, and some inflatable floatation devices that you could use, though we mostly relied on the things we brought with us. The owners also provide guests with a large information packet that is very useful for getting the lay of the land. I recommend you get in touch with them via email a few weeks before you depart to confirm trip details and open lines of communications in case something were to go awry (though everything was fine for us).
My wife and I have spent a lot of vacation time in the Caribbean (on St. Thomas, St. John, Puerto Rico, Vieques, and several Bahamian out islands) and felt that Roatan was very welcoming and easy to vacation on. There is clearly some poverty and some poor infrastructure on island, but Roatan also has many modern conveniences including excellent supermarkets and good internet. ALL of the restaurants were very good if not excellent, from local street cooks right up to the amazing sushi just a short walk from the cottage. The taxi system is simple to use and very reasonable for short trips on the carreteria principal: just walk to the road and flag down a white sedan with yellow number plate on the side (I recommend asking the driver to quote you the fare before you get in the car).
Overall, this place was comfortable, new, and easy to stay at. It made for an excellent trip that we hope to make again some day soon!
