Hi Anne, as Yannis say's - - - - - Please ask questions, one of us will answer you quite quickly.
Welcome to the forum indeed - always a pleasure to find new members and newbies to San Stefanos.
The Nafsika is a nice place for your first visit, The "Old-boy" George is the owner and Speros his son tends to do most of the General Management there. They do Greek Dancing as well! Vangellis is one of the nicest waiters, a genuinely friendly bunch.
Very Friendly and a good base, food good, nice bar, great breakfasts.
Try a couple of other restaurants, while there, opposite is the Beachcomber Bistro, brilliant meals, watch the sun go down over the beach.
Manthos Taverna also opposite does a Greek night,
but I would eat at the Nafsika and go over for the Bar and show, as you are half board.
Also try the Mythica and Ozzie Oils for great meals, Little Prince or Zorba's for entertainment while you eat,
The Condor is a music bar - plus live entertainment and tribute acts, but for all age groups - (it's not a teen bar), and you feel comfortable and welcome.
Other venues close by do shows and entertainment other than Greek Dancing as well.
Anywhere you go out for a meal will be good in S S.
Makes for a great night out - and it's all in walking distance within 5 mins or so.
Have a great Holiday.
Tony
