Great place to stay overlooking the water with nice pool. Staff is great. Location is great, close to everything but not in the middle of the craziness of Duvall Street. Room was good. General property could use some sprucing up but doesn’t take away from the overall pluses of the place.

We booked a 4 night stay for two in a queen bungalow. Online the room included a pull out sofa however this was the smallest bungalow (room 103) and did not include a sofa or sitting area. I couldn't find any pictures online but the room pictured on here is 104. It was nice to have a private patio with a pool view, but a little uncomfortable having a single pane glass door with a flimsy lock where you sleep. We ended up moving rooms for an unrelated issue and the staff were beyond accommodating. We moved across the plaza to the white house and we're much happier with our room and we're gifted an extra night at no cost for the inconvenience. Continental breakfast was included and delicious (pastries, fruit, cereal - same daily). The cafe on the property was also lovely. Everything was walkable (30 mins to otherside of island). Highlights included the butterfly conservatory and the sebago
