No, this is not a 5 star - Out of 5 stars it is a 10. Took my 7 and 10 year old grandsons this time (I've been here many times - had a big birthday bash here a few years ago) and they were enthralled. Immediately after leaving they asked if they could come back sometime. OF COURSE!!!

Definitely a place we'd go back to again! There's so much to see that your brain goes on overload. Would love to stay a night or two in one of those fun rooms!

The food was excellent and of great value. The team at O Mansion went above and beyond for our team-building retreat.

My second visit and brought my cousin Carol along with me, who also ended up loving it as much as I do! I also had the great fortune and pleasure to meet lady H who was a gracious and yet accessible hostess for the time that we were able to spend with her. Robert our young host / docent, made our visit that much more pleasurable! Not only was he able to help us with a couple of purchases that I made (which I shall cherish for a long time) he was charming, cheerful and knowledgeable about this amazing home, event space and boutique hotel as well!!
