Photo by myself around 72nd Street and Central Park West on the Upper West Side.
It's hard to resist peeping into people's apartments. It's a very human reflex.
A man was preparing dinner in a small galley kitchen, to the left. To the right, the lights were on in the Living Room. You can see the beams in the ceiling, which are typical in pre-war buildings.
The building above is a little unusual. Many of the apartments are duplex units, that is, apartments that have an upstairs and downstairs, connected by an internal stair. There are triplexes, too, apartments with three floors. The room above the Living Room is probably the Master Bedroom.
The benefit of owning a duplex is that they feel more like a regular house than an apartment building. The drawback is that the internal stair takes up precious square footage. Each level also seems small in comparison to an apartment on a single level.
There is a bit going on in the photo above. The large window on the right is metal. The windows on the far left are old, wooden windows, located in a fire stair. They look in need of a good cleaning.
There are a couple through-wall air conditioners above, where the air conditioning units penetrate the exterior wall. The air conditioner in the man's kitchen is within a window, which is not too nice looking and blocks some daylight from coming in.
