Summer at the Beach?

I have a good friend from NYC (via Florida originally) named Joe who really wants to come down for about 6-7 weeks this summer, second week of July through end of August. He's 29, a teacher and linguist, smart, fun, well traveled and well read, thinks he looks like Tom Cruise (he does not ) Wants to spend the summer at the beach, writing and running and doing yoga and yolo/surfing,

He needs something for that long a time so he can sublet his apt in Brooklyn easily. He is looking for either a furnished studio or one bedroom apt or a summer room mate situation somewhere along 30A - since he will be biking everywhere all summer.

Any suggestions or furnished apt or rooms or studios? This is a hard area for this type of rental, so thought I'd reach out!

Thanks!
