The receptionist was super helpful and let me check in early. However, the hallway is very narrow and the room was smaller than what the pic showed. I guess it is normal for inns in the downtown area.

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.
