Very Good 8.0
Great place for a get away
The hotel is beautiful. It is clean, easily accessible and a stones throw from Niagara region. The Internet was spotty at best, and there was a large unruly wedding party making noise late into the evening.

Very Good 8.0
The hotel was really nice with great service, my only complaint was the tv channels offered with very little options. Also it was very warm in my room and there was no way to lower the temperature. Otherwise overall I really enjoyed my stay there.
