So they converted a 1 living room/1 bedroom apartment into a 3 bedroom apartment by putting up some plywood which turned the living room into 2 additional bedrooms. I was in one of the converted units.
There's very little soundproofing so you can hear every movement the other units are making. Even if you get a really good neighbor, no matter how quiet the other guests try to be they will still make some noise. And if the other guests are loud and annoying then you're going to have to put up with it.
The 3 units shared 1 bathroom which was never an issue for me.
Overall it's a good value in a decent location. The place was kept really clean.
