Apartment 518

You are a group of tourists who arrived in a new city late at night, all the hostels are already closed, and you have no money at all. You come across a newspaper article with a very cheap apartment. They say people disappear in it... No, don't think so, the apartment is the most ordinary, but with the most extraordinary events. Rumor has it that the owner of this apartment has spent a very long time in prison for mass murders, but you don't care much, the most important thing is the price, so come in. Age restrictions: 18+
