Noise Problem
I don't think the walls have anything to block the noise from the next room. You can hear everything people say, even when they're not speaking loudly. This is a HUGE disadvantage. I can only imagine how it would be like when there are kids next room.
Another issue was with the AC unit. The room was freezing because there was no heat. It kept blowing cold air no matter how high we've increased the temperature. We've ended up shutting the thermostat off, and wear winter clothing to keep ourselves warm. We couldn't get fresh air since we've shut off the thermostat, and the windows can't be opened either. So, we had to open the door to get air inside the room. This was very uncomfortable.
My advice to the management: Please check the room that you're giving to your guest right before you give it, and make sure that there are no issues. For example, I would have a "checklist" on my hand, so that I don't forget anything. Housekeeping personnel do their job, which is clean & organize the room. There needs to be another personnel to run a checklist.
