The property is a beautiful oasis and the staff kind and accommodating. Good location if if you don't mind walking a little and easy to get Uber if preferred. Breakfasts were exceptional and our room/mini-cottage was beautiful! I highly recommend this property and hope to be back on our next visit.

Loved the property, great breakfast and amenities. Rooms could really use tvs to keep up on weather or local events happening. I'm not a big TV person but do enjoy watching local news and world news and weather. Like to do it in privacy.

It is a beautiful property. I was disappointed that the rooms have no TV, Microwave or Mini-refrigerator. Those seem like standard things in even a cheap hotel. And this was not cheap.

I was honestly blown away by this place! The backyard is truly an oasis - I could’ve sat there all day and have been perfectly content. We were in the Sun Room, it was so cute we definitely want to book the same room again! It was really nice to be able to park at the residence, as another we stayed at required us to park at paid parking. Highly recommend!
