The back sliding door did not lock, and is only on the second floor, with a fire escape ladder that can be reached from the ground. This fire escape provides direct access to the door that did not lock, and was only secured by a piece of plywood.
About two days in, my son got a splinter an inch long from the old wood floors, which got infected.
Additionally there were hypodermic needles on the ground outside, and my four year old daughter almost stepped on one while walking out the door.
Overall terrible experience.
