Two consistent issues were the sound. First, there was a high-pitched sound when turning on the shower. I feared some pipe or part was going to burst. It went away about 2 min into the shower, but that's gotta be waking up people in the surrounding rooms. There was some irregular noise, sounding in the room--it would come and go, not loud, but noticeable. It wasn't the air conditioning or fridge. Something coming from behind the walls. I didn't get much sleep during my stay. Other than this, no problems.
