with what you have, double usage and storage is important. maximise every inch and do away w/clutter.
will the landlord let you update the bathroom? look on FB marketplace, craigslist for lightly used vanities that you can paint.
look for throw-away marble/granite pieces that you can use for a sink top.
or buy an all in one vanity.
this sink is ancient. you could do a 30" w/better storage.
you can find older oak vanities for next to nothing, prime and paint, redo the top and it will look 100X better than what you have. bigger mirror in there will help too. cant see your light fixture.
see if you're able to paint those worn kitchen cabs. (give them a good cleaning, sand w/150-220 grit, wipe w/mineral spirits, prime (spray primer) fine sand again, then get a good wood paint. you dn't have many to do but it will make a huge diff
replace that curtain w/a blind
get rid of these horrid blinds, do something like a woven wood or solar shade.
find a used piece of furniture you can use that will give you more space on top or below
