A prison in Serbia is also home to a hotel.
When you enter through the front door of the Srem, one of two hotels in Sremska Mitrovica, a receptionist welcomes you and assigns you a room on the first floor, accessible via a fancy double stairway.
The back entrance is different.
You enter along a fenced passageway fringed with razor-wire and with an armed guard at your side. Your room is at the foot of the stairwell, in a corridor behind heavy drapes and heavy-duty bars – no other way in or out.
