The Napa River Inn. But it can be pricier than others. Great Views of downtown & more
The theater is downtown near many nice hotels within walking distance to the theater and many nice restaurants...and several more hotels are within a short uber.
There are multiple hotels in the downtown area of Napa. When I went to a show at the Uptown Theater I stayed at the Archer. A little pricey but has a wonderful restaurant.
