Super proactively responsive. My flight was cancelled in the middle of the night, so my only option was to rebook in the morning for an immediate flight or I would have missed all my planned meetings, because the next available flight was later that night. I had to land at 6am - but check in was not till 4pm. Denise replied immediately and confirmed that the place was cleaned earlier so I could immediately check in when I landed at 6am. Without that I wouldve have to take a shower at a gym and lug my bags around the city with me.
