Hotel needs to be updated. Vending machines weren’t working or sold out. Convenient location.

The staff was extremely friendly and helpful. While the place is kind of outdated, it is nostalgic in that sense. The location was great, the place was clean, the price was reasonable.

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.

For the price of a nights stay, you’d think they would invest some more money into the hotel! Rooms were clean, but old and outdated. Just as outdated as the grounds surrounding it! The restaurant was understaffed. The grounds yet again were in need of some TLC!

The pictures on your website does not represent the hotel as it is today. It is very deceiving the role I stayed in many things in the hotel was in this repair, including the doors would never recommend to anyone to stay there ever was very you are very overpriced for what it is.

Very Nice Stay

Our stay was nice and quiet and comfortable. Staff person was very pleasant and helpful. She offered if we needed anything more to let her know. If we are up that way again or someone asks, we will recommend Bonnie Castle resort to stay at.

The facility is very outdated, has not seen renovation probably since the 1990s. The doors lock with a classic turn knob key, the entrance signs are rusty and decayed. On a positive note- the place is clean and people are nice

We did the upgrade for a room with a balcony facing the river, the view was beautiful, the balcony was super small, to the point that my husband could not sit facing the water, he had to turn sideways. The resort is dated but clean for the most part. The service was mixed, The Pointe was good, The Manor was terrible and they weren’t even busy. It was convenient to the boat tours and shops.

The lady staff mixed up my friend’s booking and was very rude to her (in front of me). My room is also very dusty. Toilet amenities are also bad quality for $250 a night.
