Agreed with the other poster, if you want something where you can just lock and walk away, an apartment maybe more ideal. Imagine having a TH, you are away, and mail starts piling up. Will be a massive sign for potential trespassers that no one is home.
I agree apartment in many ways (space, HOA) is not ideal as well but given the divide between your apartment and street level, coupled with a lack of stairs, I do think it may be a better bet. Either that or a TH in a more TH community setting with lots of neighbors so that you at least reduce the chances of a break in when away (but the massive amount of stairs will be annoying).
If apartment here is one I just saw, 3BR, decent Sq footage, and very walkable (can't comment on price as I don't have much experience with apartment pricing plus I find, due to my own inherent bias, to price them fairly since I feel they tend to be overpriced compared to TH options...but that's my bias I feel):
