The hot water in the main bathroom would go out randomly. Even if we just got back from the day and hadn't used any water. The back bathroom & bedroom smelled like mildew. We put a cup under a leak in the master bath to catch the drips before they saturated the carpet. That might be where the mildew smell is coming from.
Lastly, there was construction each weekday morning starting very early in the apartment below. Most places let you know if there is going to be construction noise during their stay.
Location was great and was close to everything.
