The property was located in a very quiet area. It is very evident in some locations of the resort that service is extremely important. The Hilltop & Boonfly Café were consistently on top of service. The restaurant Farm lost points with us after a follow-up call was not received pertaining to reservation availability. The cottages themselves were very cute and had excellent amenities. The fireplace, fire pit, and outdoor tub/shower were so unique to our cottage experience. The cleanliness of the outdoor pillows, the curtains, and rugs were not pleasing. The outdoor rugs and cushions in the outdoor seating areas, particularly, near Farm were filled with pet hair & the floor rugs need to either be cleaned or replaced. The overall disappointing piece of the resort was the cleanliness. Even the hot tub had grime. With the amount of money paid to book the resort along with monies spent at the resort, there needs to be some revamping of the care.

We have been going to Solage since 2010. Back then it was the nicest property in Calistoga. The problem is that that management has upgraded since 2010, or so it feels like. Pros are the following: 1. Property is still manicured well with staff on site ensuring both cleanliness and aesthetic. 2. Spa is still pretty nice. 3. Service was solid, overall..not the best but still in the top 10-15% of hotels. Cons: 1. Property has not been remodeled in some time and it shows. While it’s well maintained, the technology is nonexistent and quite frankly outdated; 2. Solbar does not deserve a Michelin recommendation or star. It was so disappointing. For starters the bacon was clearly thrown in the deep fryer, not cooked on the griddled. The smashed potatoes they are known for weren’t crispy and it appeared as though the oil wasn’t changed for many days. The fruit bowl was clunky. If I’m paying $16.00 for a fruit bowl, you should take the time and peel the fruit, present it nicely and make it beautiful. It was not that, just thrown together with little to no care. Dining room was load with kids. This is supposed to be a relaxing retreat not kids running around like Disneyland. If I wanted that experience I would go to the OC. Needless to say I did not enjoy paying $150 for breakfast and have such an awful experience. 3. A few more comments on the room and being outdated and old. The property is pretty dingy. The common areas are not well maintained.
