We had a great stay and would recommend this to others. The place is very relaxing and great value for the stay. It's exactly what we needed for rest and relaxation and we will go back in the future. Yes, the unit is attached to the main house but it really is very private. As one other traveler noted some noise transfer between the bathroom and main house, but not a big deal at all.
Jeanne is a great host and they have a wonderful spot. On a selfish note, I hesitate to recommend it too much as it seems like it will book up fast in the future and I don't want to miss out. Great island and great place.
