ZSL London Zoo

The hotel was very clean and conveniently located. However, when I checked in (quite late), I told the front desk clerk I was looking forward to getting some sleep before the next leg of my trip and was glad I didn't have to check out until noon because it had been a long trip and I needed some sleep. I was very tired and put the "Do not disturb" sign on the door and went to bed. Unfortunately, housekeeping began knocking at around 8:30, and not a gentle tap either. They kept knocking loudly until I got out of bed to go next to the door and yell through the door that I was still in the room! (Yes, I had the Do Not Disturb sign on as well as the security lock and deadbolt). This knocking and my shouting that I was still there kept up hourly or so until I left, still exhausted. It was very frustrating to have been awoken like this; jet lag and fatigue is a reality for many travelers. I booked a hotel in the hopes of getting some quality sleep! I think that overall the Hyatt can do better than having housekeeping pound on people's doors to see if they've checked out early-- I mean this is the age of AI, etc. Surely we can scan our keys to indicate we've checked out and then housekeeping can go to those rooms where guests have checked out early so they can complete turnovers on time? If that's not possible, just say checkout is at 9AM-- I would've booked elsewhere. Writing this review to let other guests know that Do Not Disturb signs are roundly ignored here.
