"Great food, great people. Facilities feel dated."

6.0

Staff were exceptional. Food services, spa were all above and beyond

2 mornings in a row we had no hot water in out room. First time someone came right away. Second day, when we were trying to check out, took 40 minutes.

"The rooms are beautiful"

Great stay beautiful rooms amazing staff

The spa itself is dated. Everything else is amazing not worth just a day trip to the spa.

"Very Good"

7.0

The facility in general was nice. The staff were friendly and helpful. Almost everywhere was very clean. The room in general met our expectations. Beds were comforty. Bathroom was very clean. Spa was one of the reasons of our choice and it was very beautiful to enjoy pond and the sauna.

The heating system was too noisy. We have changed our initial room with a so called better option as the first room was too noisy because of the heating/cooling system. We thought it was broken or had some sort of malfunction, but the new room had similar issues so we could not, literally, sleep until morning because of the noise caused by the heating system. Although i turned it off, it kept working and turned our night to a disaster. This was the only, yet an important, problem with the place. This is the only question that will affect our decision for a possible another trip to this facility.

"A restful retreat to get away from the everyday routines and unwind."

8.0

We stayed in the Croft accommodation and it was quite private having our own hot tub and beautiful cedars to look at also enjoyed hiking the grounds, very peaceful and relaxing environment.

The Croft accommodations are tucked a little bit away from the main Hydro pool with a fence that unfortunately, you can’t access unless you go around to the entry of the spa a little bit inconvenient when you’re in a robe and sandals! The Day Spa clients can use the change rooms and go right in from there.

"Very nice/relaxing hotel and getaway"

8.0

The hotel room was very nice, clean and comfortable. I enjoyed the spa and massage service I received. The outdoor amenities are nice.

I didn't like the restaurant or food options/quality of food. I found it overpriced for what I got, They can use more restaurant options. I'd recommend add a modernized cafe and expanding/adding to the current restaurants. The restaurants could also use renovations.

"disappointed, needs some TLC"

4.0

the rmts were great

the spa reception was sad, didnt want to be there. We were looking at product and she didnt offer to assist, we didnt purchase anything due to this The spa change area was dirty, towels were poor quality The jets outside hot pool were low wet dirty towels left everywhere the indoor pool space feels sad, needs a bright coat of paint and some beautiful plants Pillows in room were old, very soft, no hand soap in room, shelving in room and outside of room had paint chips everywhere, the place is historic and beautiful but needs a facelift. We have been here several times and it continues to lack lustre. For what we pay a night, the place should be a bit more presentable, it didnt feel clean. Its a beautiful property, not sure whats happening there.
