If I knew that there was a laundry room, my stay would’ve been 11/10 but that’s on my part for not checking hahaha

Small room but everything else at the hotel made up for that fact. Good location, friendly staff.

We got zero sleep. There were protestors outside the hotel lobby by 6am. The hotel said only you can return the funds.
