I'd redo the living room layout

in small spaces, sometimes the bigger you go the better you get..when comes to incorporating all kinds of storage

so. I'd try to do some sort of a wall system incorporating your TV, books, working space even. whatever else you need to there on one wall..the longer one I guess, with no windows.

sofa goes betwwen two windows, and the whole conversational shebang you need there..a chair, a coffee table//ottoman, a side table..angle the chair as on your scheme..

you'd be able to turn the TV a bit my guess is, for movie nights and all, if you'd feel the angle is still too wide between TV and you.

dining area gets to be more floating (consoles/sofa tables look good behind sofas..dining tables are too high for that, you won't like neither dining nor sofa..and also food might fall onto sofa..would happen to me lol)

I'd make it (a dining table)round probably..with a possibility of additional leaf-never hurts..but in any case, it'd go next to the kitchen(obviously)..approximately where currently window with curtains is. more defined dining area. that can still be maneuvered around

tell us your style-and we can be more helpful with pointing out pieces/stores to look at

as for decently priced..whatever your style is, always check vintage too. Takes time and patience but one is rewarded in the end

as for your bedroom I personally love books in bedroom..I might go for lighter colors/same as future walls color in order to make shelves less obtrusive, more built in look

don't forget lamps -floor ones, table ones etc.

rug/s in living will help to define different areas

that's my very general take

nice apartment with all the challenges..Manhattan sounds exciting! love Mahhattan. Have fun putting your new place together

PS you know website "Apartment Therapy"? they also have couple books published. Great sourse of inspiration for small spaces

I really like your dining-table-as-sofa-table solution in this space.
