Pay attention to the cleanliness of the apartment
If you find yourself staring at a dirty apartment, don’t rush to sign a contract. It’s possible there are even more unpleasant drawbacks hidden behind the mess. You can ask the owner to clean up, but be prepared for them to simply refuse any further discussion and ask you to leave.
If it’s only the dirt that’s causing you to feel doubts about the place, don’t rush to give up on it. Thoroughly inspect the apartment — that way you can decide whether you can bring it into a normal state on your own.
