The room was clean and comfortable. The staff was helpful and friendly. Convenient location. Although there is no parking offered through the hotel, there are lots of options that are reasonable and nearby. We needed an in and out option and found it right around the corner.

We called and the man in the morning was so rude when we asked about the check in process. He told us we could check in early however he let someone else check in early? I was confused because he told us that everyone’s check in was strictly 4. Glad he was gone by the time we got back from eating because the next employee was there and he was so nice and accommodating.
