Just moved down here

I (single 40F) just moved (temporarily staying with my sister in Mission Bay) down here from Los Angeles. I’m looking for an apartment in a more walkable or bike-able, less family-centric area. Also hopefully a little cooler (temperature and vibe-wise) area. I’ve heard East Boca is a little livelier with more to do than over here. Also, I’m open to other towns nearby. Delray and WPB are a little farther from my office (in Coral Gables and I probably have to drive down there once or twice a week). Maybe even Fort Lauderdale? Would love some recommendations on neighborhoods to look at. Thanks!
