Run Away! Health and Safety Hazard!

Hi Gail, Lindy and I were sick after staying at your Riverside Hotel and Spa on 5/18/25. We let Hailey, the receptionist, know that we were sick after using the mineral springs at the hotel and we also smelled a gas smell downstairs. We checked out on May 19th and let the receptionist know to also cancel the reservation for the 20th. We also witnessed others checking out, and others were getting sick as well. This is a public safety and health hazard that needs to be fixed so that others do not get sick. We should have never been charged for the night of the 20th as it was cancelled when we checked out on the 19th from being sick at your hotel. We also should have never been charged for the 19th. We also spent an additional money at the local grocery store for pain pills, OTC medications, and supplies to treat our sicknesses from staying at your hotel. We should also be reimbursed for our time, travel expenses, medical expenses, and distress from staying at your hotel. This is unacceptable, immoral, and very corrupt that you have not been willing to work with us or even speak to us. This was supposed to be an enjoyable relaxing weekend getaway as part of our 20 year anniversary and celebration, but turned in to a disaster at your hotel.

Good 2 night stay!

This is an older historical hotel. It is hard to keep an older place up. Carpet a bit worn but overall a good experience. All the staff were friendly. The bar & restaurant on site were Excellent. Chef was top notch. Our scallops were cooked perfect. The 2nd night we had lobster and it was good. A+ to the bartender!

Lovely, quaint, historic establishment.

This is a lovely and very old historic building. This is an adult only, dog loving establishment, which is wonderful. If you are looking for modern and chic, keep going. If you appreciate history and the quirkiness of old establishments, you will find this place charming. The dinners in their dining and bar area were outstanding! The barista bar had very good offerings and coffee. They have very nice hot spring pools in their full service spa. The service and friendliness of the staff was very good.

The whole trip and experience was 5 star!! From the time of check in with Dave who was very helpful and informative to the dining and lounge experiences with Will who was an excellent bar tender best in the area and as well as Rachael and one other individual who was waiting tables. The inn is very unique and a one stop for everything. The little eatery within the Inn was fatastic as well not a bad thing on the menu. The final checkout with Cat was also a great experience she is a very fun and casual person. All of them were very friendly and professional and treated you as if we had met already before. I will definitely be going back to have another 5 star experience! Thanks to everyone there for making the stay a very memorable one.

Charming Historic Stay with River Views & hot pool

My husband and I stayed here for a relaxing overnight getaway to celebrate his birthday, and it was perfect! This charming historic hotel, built in 1914, has so much character, from its original creaky floors to its unbeatable location right on the river. Our room had panoramic river views, and we loved cracking the window open to hear the flowing water—so peaceful! It’s right in the heart of town, with Eruption Brewery next door (their smash burger was delicious!) and the hot springs just a five-minute walk away. The private hot pools on-site were a highlight, and while we didn’t have time for a massage, it’s a great option. Breakfast from the café in the lobby was included with our stay, with a nice selection to choose from—I went with the quiche, and it was delicious. The hotel also has a restaurant, which we didn’t get a chance to try. From the spotless room with its personal heater to the thoughtful bathroom ceiling fan with a built-in warmer, plus the friendly staff and relaxing hot pools, everything was wonderful. We’ll definitely be back!

All you need for a comfortable nights stay, plus the history! Hot spring tub rooms were relaxing and private, dinner was sublime. Plus we enjoyed breakfast at the onsite coffee shop. Snowed 10 inches when we were there. Staff kept us safe and warm. In fact, all the staff we met from the hotel were very helpful, and enjoyable company. Thank you!
