I kept my Catalina 27 in Marina Harbor marina in A basin in the mid-late 1980s. I don't know how they are now, but I really liked the A basin location. Parking was plentiful, and I liked the fact that it was closer to the entrance channel. I was at the westernmost part of the marina, and the apartment buildings really helped shelter my boat when the winds came up.
Used to sail into/out of my slip a lot. Sailed in the gentle evening breezes in the main basin a lot. Very peaceful and relaxing.
Good luck on your search!
