Diane (I think that’s her name) is so friendly and fun at check in - she’s amazing and makes sure to explain ALL the things! The soaking tubs are amazing. The staff is all friendly. You can easily walk to the Lava Hot springs pools and there are some great dining options close The hotel itself is older but very well kept and a perfect getaway from the busy city life 💕

The property was convenient to the river for tubing, hot springs, and food options. Parking was close and free. The hotel was very quaint and quiet, and we appreciated the gift of a discount for tubing, the free use of hot springs rooms onsite, and the tasty breakfast that was included. There was even a room upstairs with jigsaw puzzles. :)
