My husband and I stayed at the Solage Calistoga for two nights for our anniversary. It is not an inexpensive hotel, but I got the Go Outside and Play package and had the most incredible experience. The hotel is very clean and has a zen like feel - rooms, bathrooms are gorgeous, pretty private patio and the service was excellent (a little hiccup at the spa - my massage therapist was excellent, but my mudslide therapist forgot about me - not sure she apologized, but later she did offer me a free smoothie - nice gesture, but it wasn't that busy and surprised that happened).
Love the 4 hour use of a mercedes - we were able to take advantage of this (it's on a first come fist serve basis) and loved the 2 seater convertible driving up Howell Mountain (appreciated the help booking our reservation at Outpost and Tamber Bey) - gorgeous ride and views!
We also loved the "old fashioned" bikes outside our room and had a lovely bike ride around the area. Great fitness center and liked that the instructor was very nice with "allowing me" to continue to use the "fitness class" room when she started a class (I was out of the way).
Solbar breakfasts - Scrumptious - love the variety and different items they offered. The Sol-pe was sooo good and delicious cinnamon sugar donut holes! Very modern, clean and tranquil ambiance and service was both friendly and exceptional.
Great location for our Napa area wine tastings!
