LOUD Rooms!
I'm currently staying at the Residence Inn Oldsmar, FL. If you want a hotel you can actually sleep in this is not the place for you. The walls are thin enough that we can hear the man next door snoring. All night long! We have a 1 bedroom and the AC unit is right next to the bed. I kicks on and off LOUDLY every 15 minutes. No way to turn it off. The cleaning staff kindly runs the dishwasher for you daily, but it too is as loud as a freight train running through your room. It runs for an hour. The refigerator is also quite noisy, cycling on and off. And if you want the bathroom light on you get the fan too. It emits a whine equivalent to a jet plane!
For a newer hotel it is obvious that Marriott cut expenses by using subpar building materials and appliances. I will deffinately NOT be staying hear again.
