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!

Excellent staff, clean rooms and great experience

Our stay at the Riverside Inn was everything we hoped it would be. The staff were all so friendly, helpful and always available. Our room was spotless and had a brand new comfortable bed. I would stay here again!

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!

Not As Advertised

This hotel is very old and in poor condition. It does not look like the pictures on the website. I had to sleep with layers of clothes because the old fashion heater could not keep the room warm. Breakfast was one item heated in the microwave with one beverage.
