My fav in the Niagara Area
We always stay at the Stone Mill Inn. It’s close to family and all things Niagara. The Inn is up to date, has all the amenities I need and a very comfortable bed. The restaurant below is great for lunch or dinner and behind the Inn is a Starbucks and grocery store plus more food shops. Easy to get to.

Incredible value in a boutique hotel
This is a great place to stay! Its an amazing conversion and renovation of a heritage property. Very large and clean room. It is also very quiet and great for sleeping. The staff are friendly and helpful. This is a large boutique so it has advantages.

Charming and lovely hotel!
We only spent one night here but we would definitely stay here again. Our room was lovely, with exposed stone walls and very comfortable. In addition, the entire room was clean and spacious.
The hotel rep that checked us in was friendly, courteous and completed check-in quickly.
We went for drinks in the attached restaurant and again, our server was extremely pleasant and friendly.
The area around the hotel is convenient and we were able to walk to local restaurants.
I would definitely recommend this hotel to anyone visiting the Niagara area and we would definitely stay here again.

One night stay
The experience with front desk was great - they were very pleasant. The room itself was huge. The couch was quite uncomfortable since it was leather. The bed was good. Only issue was the fact that the lights are turned off in the hallway at night. Apparently they are motion sensored but just doesn’t feel safe having them turned off after a certain time.

Overall it's very good. But it could have breakfast included, it would be much better, and there could also be things in the minibar for us to buy.
