no mice or roaches here...knock on wood! The only annoyances we have are wasps/hornets in the summer and the occasional beetles and thousand leggers due to the small creak that runs behind our unit. But I've found that they're everywhere in Jersey.
No, the apartments are very clean. The only problem that you will have is that if you live on the bottom floor, spiders will crawl in from the outside. Personally, I hate spiders, so I found this to be annoying, but it in no way reflects on the cleanliness of the apartments. They are surrounded by woods and spiders live in the woods, and are bound to get inside.
