Those of you who are using apartment antenna I would love to know of
your experience.

I had a nice cw qso with a fellow in an apartment using a 9:1 unun made
by balundesigns.com to a straight wire off his apartment balcony to a
tree. Such a wire could be made very small and almost invisible, if that
is a possiblity. Also, easy enough to homebrew your own 9:1 balun for
such, if you are inclined.
If you could feed with parallel line, an end-fed zepp might work well,
but would require an end support, such as a tree, and the parallel is
more visible.
If the second support is not practical, many have used coil loaded
verticals off a patio. This could be done with a collapsing fiber glass
pole for removal when not in use.
Both schemes would require a tuner.

A screwdriver antenna may work better than the Hi-Q loop. I'd check at
eham.com reviews.
