Broken tiles and unsafe environment; kitchen sink flooding the floor. Maintenance lacking all around.
Lack of care by host to come and secure the bathroom after the tiles fell ("due to heavy rain"), even when I had a 2 year old baby with me; he mentioned insurance employees would have to be involved, and didn't revert.
Lack of garbage bags, garbage cans, and only one set of keys for a 4-adult apartment.
Not even a doormat (only apartment without in the whole building) to wipe my shoes when they were wet: we later got scolded for leaving shoes right outside the apartment door.
Hosts' politeness in messaging cannot make up for a poor, unsafe level of service.
