We spent a week in Margherita and really didn't want to leave. It was spotlessly clean and well-maintained, beautifully decorated, with a private terrace with amazing views over the sea. We loved it.
We didn't see much of Sheila, the lovely owner who lives next door, but she was extremely helpful. She told us it was feasible to walk down the hill to Agios Nikolaos, with its beach and tavernas, but to be honest we were in need of a totally lazy holiday (and it was only a short drive).
We did a couple of trips out, but we liked Agios Nikolaos best and returned there every day for a swim, a read on the beach and something to eat and drink. It's pretty and was quite quiet in early June. Our favourite place was Taverna Porto, run by Dimitri Theodosis and his family, who also run some of the boat trips. Lovely, friendly and welcoming - we felt like old friends by the time we left! - although in fact we didn't meet a soul while we were in Zakynthos who wasn't friendly and welcoming...
