I like my apartment, but I don’t like the neighborhood.
I like my apartment. I don’t like the neighborhood, though.
“Though” is used sometimes just like this, instead of the word “but”. You use it when you are trying to emphasize the difference between ideas.
You can also say, “I like my apartment, though I don’t like the neighborhood”.
These days, some people will write “tho” instead of “though”. And they say cats are lazy!?
