This is a one bedroom apartment with three beds. If you look closely at the photo of the queen bedroom, you can see the wall is a partial wall. Anyone staying in the den can sit up in the top bunk and look in on the queen bed. The bathroom is only accessible from the far corner of the bedroom, so anyone staying in the den bunkbed needs to go across the bedroom at the foot of the queen bed to get to the bathroom.
The apartment was very clean and in a great location, so as long as you are not expecting any privacy in the bedrooms, we highly recommend.
