Let me start: So basically I was in really cheap, crappy hotel which had a pool but the walls around it had some really bad mold. The first room I got smelt like cigarette smoke and the sheets had stains all over it. The second room was MUCH better thank god.
Accidentally booked in a bad part of town. Front desk was behind bars. The room was nothing like they showed online. Later we ordered delivery and they refused to leave their car.
Another time we did a test flush before using the toilet and the handle broke. Front desk was rude as hell. Someone fixed it within in an hour. The maintenance lady said it was common and they have been replacing them with upgrades as they break.
