My wife and I stayed overnight here in late last October after spending the day at Lowell Observatory, which was the main reason we had come to Flagstaff during our Arizona vacation.
Our stay was adequate. The room we got on the second floor was clean. Road noise was not an issue. The breakfast in the morning was good. The hotel does not have an attached restaurant. On the advice of the very helpful and pleasant person at the front desk, who named several nearby restaurants, we chose to ate dinner that night at the Olive Garden a little ways down South Beulah Boulevard, which is conveniently accessed using the hotel's back entrance/exit.
One constant problem we experienced during our brief stay was the keycard access. It was extremely flaky. Even after ensuring that nothing electronic or magnetic got near the rescanned keycards, they didn't work reliably. The person at the front desk told me that the hotel was due for a renovation soon. If that happened pre-COVID, perhaps the problem has already been addressed.
