With a week to spend in Napa Valley, I chose to split my time between accommodations in the cities of Napa and Calistoga in northern Napa Valley. This was done mostly for convenience; while the distance between the two towns is not great (about 25 miles), cutting the added travel time driving back to Napa every evening, sometimes with significant traffic, from visits up north is greatly appreciated.
In Calistoga I chose a very affordable option, the Comfort Inn on Lincoln Ave, just on the edge of town. It's about a 12 minute stroll down the avenue into town, where you can find a supermarket, shops and plenty of dining options. The accommodations are relatively basic here, clean, spacious, perfect for a home base for a couple of days. One nice feature of the property is that even this simple place lets you take advantage of the soothing mineral spring waters Calistoga is famous for. There is an outdoor mineral fed-spa on the property that was a rejuvenating treat to take advantage of after a busy day.
