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.

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!

Amazing hotel, amazing breakfast. Only issue, which is not a hotel problem is the street noise, you hear the traffic and people walking past the hotel at all time during day and night.
