My windows face the front of the house, on a suburban neighborhood street. There used to be a few large trees in our yard but the hurricane knocked them all down.
Mostly a parking lot, plus another apartment building, a bit of green space between the buildings, and a railroad track next to the parking lot.
EDIT: Now, the place I was living until last year, I literally had the best view in the entire city of Bozeman, MT. Living room and bedroom windows looked straight out at Mt. Baldy (the closest mountain to town, and dominant on the horizon), from the ninth floor.
From the window on the left side of the bed, I can see the side of the neighbor’s house, and part of our dogwood tree. From the window on the right side of the bed, I can see the back of the neighbor’s house, their deck, and their back yard.
With just the blinds raised: mountains, the tops of nearby houses (mine is highest on the slope and I’m on the top floor).
If I lean out, I can look down to see the little square downslope, with the mini-roundabout; a couple of shops; parked cars (usually including mine). Or I can look to the sides and see closer-up mountains to the left and cultivated fields to the right.
I see some Canary Island Pines and most of Nantucket Court.
I don’t look out my bedroom window, due to an irrational fear of finding someone else looking* in*.
If I did look (and my view was not obstructed by a stalker) I would see my small backyard with a shed. I have another window that looks out onto a small street that runs next to my house and ends in a cul-de-sac.
I see ugly suburban townhouses in every direction, very close to us. I also see a lot of cars and a very few trees. Our tree has a neighbor’s deflated Mickey Mouse balloon stuck in it. It leers at me as I lie in bed.
A state highway. There are some decent trees in between my bedroom and said highway, but it’s always visible. And audible.
Doesn’t really bother me, though. I prefer ambient city noise and light to pitch-black and nature sounds only. I do worry it will make it harder to sell the place when I move on. Only shock ever - hear a loud crash, jump out of bed, look out the window and I see a truck has drifted into incoming traffic and smashed into a car head-on. Nobody was hurt (I saw both drivers outside their vehicles, standing and looking ok, kinda rubbing their heads and trying to figure out the situation) and I could hear the police sirens wailing as they approached. So I just shrugged and went back to bed.
Trees, trees, more trees. Hills covered in trees. A gravel logging road where trucks sometimes rumble by loaded with trees that the Ax Men have cut.
Did I mention the trees?
My grapefruit tree and mountains in the distance.
We have a sliding glass door instead of a window. It takes up most of the wall. I see my back yard, specifically my vegetable garden and the small patio right outside.
I can mainly see the back side of the duplexes and apartment houses across the alley from me, alongside several trees. I can see people from their windows and back porches, but it would be way too obvious if I tried to stare at them.
Buildings. Can’t see anything beyond 100 yards or so (except for a handful of taller buildings). Also, five trees in front of one of the closest building. That’s it.
My building’s parking lot, and the used car lot up the street. 
We have a corner unit on the sixth floor of a 36-story condominium. Our bedroom is in the very corner, and we have windows on two sides.
On one side we have a view of the grounds of a mansion next door, owned by a sugar tycoon. Another side has a nice view of a beautiful Chinese-Thai temple.
Good question. Sorry about the long post.
In my old house in W Yorkshire ('06) it was a small front garden and the house opposite, then some woods (why the street was called Woodside Avenue).
In Bradford city centre it was the communal grounds of the apartment and Manningham Lane (where the riots usually take place).
In China it was the school basketball pitch and running track, with Wuhan city in the distance and about a dozen cranes and construction sites.
Saudi it was a wall, outside my ground floor apartment.
Next in Saudi it was the villas on the other side of the compound.
In Kuwait it was a big expanse of dirt where buses parked, with some ruins from Gulf War 1, a highway and other high rises almost a mile away.
In Korea it was a small area of dirt and lots of other apartment buildings.
Next in Korea it was a private drive and the apartment building opposite.
Again, in China, it was a school sports field and running track outside one bedroom and the grounds and swimming pool of our gated community outside the other.
In Oakham it was a huge cricket ground.
In Islington it was a typical N London street.
Now it’s farmland, as far as the eye can see (the wheat was cropped a couple days ago).
Yes I live out of a suitcase.
The courtyard of my building. I was pleasantly surprised by how quiet it is for sleeping, removed from the street, and with (also surprisingly) quiet neighbors. I plan to stay here a while.
Back yard, row of trees beyond, then a cornfield.
The sky. Possibly a bird’s butt if he’s perched on the rim of the skylight.
I see the rowhouses across the street, iin the winter I can see the Washington Monumment off in the distance.
