The grounds were beautiful. The room and view were beautiful and restful. The bath tub was large and very nice to relax in. Unfortunately, the mattress was a sink hole and not supportive. I did not sleep well. The fireplace was beautiful but the fan was not working correctly and very noisy, even without the fan it was noisy. We were too tired to say anything and move rooms. We had dinner in the grounds and it was delicious. Breakfast had perfect bacon and jam from heaven.

So overall I’d say the inside of the property is immaculate with very nice views. However, there are zero trash cans placed around the property for pet waste even though it’s “pet friendly” and you either end up taking it to the large dumpster behind the check in counter or you use one from inside and place it outside. Also, there’s a lot of walking up and down stairs so it may not be suitable for some folks. Plus, use caution on balconies with small dogs and small children as the slats are pretty wide so there is potential to slide thru.
