Room was not cleaned when we checked in. Housekeeping took almost an hour to get to our room, after we requested their service. No doubt the front desk was nice, and followed up on us about half hour into it, but it was still an hour before we got our rooms cleaned.

The rooms smelt like smoke even though it was a non-smoking room. There were no fridges, microwaves, or even a coffee maker. =/
Output:
NEGATIVE
