Hotel is extremely dated and you are issued actual keys for your room. Our room had no secondary lock or peephole on the door. The lock could have been easily picked by a child. Also there is no lock to keep people from accessing the hotel hallway from the outside. In addition, there are no elevators to access the second and third floor rooms which is clearly an ADA violation. One of the worst hotels I’ve ever been to.

We had a great time here. Close to the village. We had the indoor pool to ourselves . Not enough time outdoor pool. In our building there was only 1 other car. No restaurant or pub opened it was a Monday so needed to go into the town. The room was average but definitely dated. We stayed here years ago when our girls were very young.

The staff and location were wonderful. We were scared when we walked into the Manor Restaurant because literally no one was there on a Saturday night - we had a wonderful dinner overlooking Boldt Castle. The prime rib was excellent! The hotel and property have not had an update since probably the 1970’s but it was clean.

Room is spacious but in need of repairs. Gaps between tiling along tub in bathroom, mold on ceiling tiles above shower, and 2 outlets didn’t work in the main room. Doorknob didn’t want to turn half the time and the room was musty despite the AC running.

Well maintained motel by a lake.

Well maintained motel in attractive location opposite Boldt Castle in Lake Ontario. Nice big outdoor pool. Can walk to the restaurants of Alexandria Bay. Be aware that they sometimes have motorcycle groups staying there ( noisy engines). Easy access to Canada via nearby 24/7 border crossing.

Me and my Thai friends were treated like garbage by the front desk staff on June 20,2025 around 430-5pm. Your staff member claimed she couldn't find our reservation when we told her our names. When it took us a moment to look up the reservation on our phones the elderly white woman yelled at us telling us to spell our names and when we laughed nervously she yelled at us that it is not funny. She was very rude and racist. Instead of politely asking us to spell our Thai names she berated us like we weren’t human beings deserving of respect. I’d advise all non-white travelers to stay clear of this hotel and spend your money elsewhere.

The hotel/Resort is run down the pictures online must be 20 years old. The building was poor condition things were broken, stains in the ceiling the jacuzzi tub was broken the shower was broken. The hallway swelled they did an upgrade but charged extra for it. Worst hotel experience ever! This place should be gutted and redone. The only good thing was the girl tried to clean but things were just too old to make look good again. Front desk was nice but the up charge for a terrible room was crazy! $300 a night for a $50 hotel room don’t stay avoid at all cost!
