People have yes, especially since we're talking about the city of San Diego. Assuming normal traffic conditions, getting to the Clinic in TJ from Downtown San Diego takes probably 30-ish minutes. It's getting back into SD that can sometimes take a while (especially at certain times of the day).
My suggestion: stay in Tijuana (Grand Hotel, Marriott, or an AirBnB) if your trip is no more than 2-3 days. San Diego makes more sense if you're there with enough time to vacation. I should also point out that San Diego isn't inexpensive either, so if you're already budgeting for the trip, you'll get much better rates in Tijuana + having the convenience of staying near the clinic.

That said, I would double check with Avanti Derma regarding the current status/travel restrictions at the border in real-time, since that can impact border crossing times.
