We visited The Cloister a few weeks ago and we were very impressed! I had not expected it to be nearly as nice as it was. I have a feeling that going a bit off-season helps.
Gorgeous suite in the main building. Terrifically personalized service at every point of contact.
We also stayed at The Sanctuary later in our trip and I would rate The Cloister above The Sanctuary.
Here are some photos and a trip report for anyone interested:
