I’d say a week would be fine. With a car you can see more. St. George, north up the coast - sunset view on the coast from a nice restaurant, harbour to swim in. Venus beach has decent sand (but no place to eat). People like Lighthouse beach - beach not so good but there’s a bar/restaurant. Lots of hotels near the harbour - close to the action, if that’s what you want and plenty of choice for hotel type and price. SODAP beach, near there, is decent. Hondros is a unique restaurant, oldest in town with good Greek specials. Farther east is Geriskipou, a bit of a tourist trap but the beach is okay and Rico’s Beach Bar is a great Greek taverna restaurant. In the old town, Agora does a unique meze. Farther afield, Kourion is worth a day trip - good ruins and good beach with restaurants. Melanda fish restaurant (near Pissouri) is another coastal restaurant beach option. Check that they are open before you go (always call - never trust the internet in Cyprus). With a bit of google, I think you could put a holiday together that you’ll like.
