From the beginning to the end of our visit, the hotel and its staff was exceptional. The check-in process was smooth. The breakfast staff was friendly. Facilities were very clean and when we had a problem with our sink faucet, repair staff was expeditious in tending to our needs. We would absolutely stay at this hotel again!
