The place maybe can fit 5 people. However, no one sleep well. The bedroom mattress was the worst ever, the sofa in the living room it's not a bed and the folding bed was super bad to sleep on.
Most of the cabinets are off and can't be close.
The water heater in the shower is not let the right water temperature to come out, either too hot or too cold.
The cleaning person should be there daily, included in the weekend, even if the guest need to pay extra for it, you should offer this option. It's no air conditioning system in the entire apartment. It's should be part of it.
