The house is completely intact but also almost entirely empty. It's a little one-story flat with two bedrooms, a living room, a kitchen and an office. The beds are left unmade, but there's no sign of struggle anywhere. There's a skylight they can use to get to the roof and get a good view of the city.

Unfortunately, the pantry's also been emptied, but they might find other useful items in the house: a vacuum cleaner, a space heater, tabs of iodine, signal flares, binoculars, sleeping bags, kitchen knives, and other odds and ends. The door to the house is still locked, as if someone was intending to return home and just never got to. No water is running through any of the taps.

They'll have to break in to enter, but they probably won't have any compunctions about that.
