Overall, property was in good condition and felt like a safe and clean environment. Had an big issue with our room (408), and our friends in another room (423) had same complaint. The smoke detector in the ceiling flashed a blue/green light every 30 seconds ALL NIGHT LONG! I can tolerate a lot of things in a hotel room, but I do expect a dark, quiet room in which to sleep. That would be the main requirement, I think. I can't imagine what possessed Hilton or this location to install flashing smoke detectors in a hotel room. Crazy and very annoying. What if a guest has seizure issues or PTSD? You will could incur big liability with that flashing light! Replace them ASAP or expect to lose bookings to Holiday Inn, which I'm sure doesn't have strobe lights in their rooms.
