Two separate things here...
This morning at 8:45 am, I came back from breakfast and as I was about to shower, a cleaning person came right in without knocking. I was certain I had manually locked the latch, but didn't notice the L-shaped upper door latch "deadbolt". The front desk said that their keys won't open the door knob latch, so I guess I might not have locked that, but I really thought I did. Either way, double-check the locks...
As a word of warning for travelers, they have a strict 3 pm check-in policy. I travel a lot for work and sometimes get to hotels a bit early. Most hotels just let you check in if your room is ready, or otherwise let you know your room isn't ready yet. This hotel wanted to charge $25 plus tax for me being about 2 hours early...Just something to consider if your travel may bring you to this hotel early, so you'd be better off with a different hotel.
