This is an excellent place to stay. So many little touches that you appreciate. Not many restaurants in walking distance, but several just five minutes away. We stay here a few times a year as a one night stop. This will now be our go to hotel each time.

Hotel bathroom was roomy. Bed was comfortable. But the fitness room was small compared to other La Quinta and one of the machines was out of order. Also noticed a homeless person lounging in the parking lot.
