Our one-night stay here was a most pleasant surprise. We made a last-minute reservation and the rate was unbeatable. The room was updated, spacious, beautifully appointed, and quiet. The king bed was wonderful for a good night’s sleep. No complaints whatsoever. Highly recommend if you’re on the road and need last-minute lodging.
