A small town which is only recently coming to the attention of the tour operators. It has a lovely harbour and is a very popular stop off point for the "yachties". whole flotillas often berth here overnight and as a result the harbour front tavernas can be very busy.
There are great views across to Ithaca from Aghia Efima and lots of small coves can be found very close to the resort where you can sunbathe........you could well find you are the only one on the beach you find! The beach in Aghia Efima itself is very small and pebbly so unless you want to venture out you may well end up sunbathing by a hotel pool. There are a good selection of shops and tavernas in Aghia Efima and most of the accomodation seems to be within a 10 minute walk of the centre.
As a base for exploring the island, Aghia Efima is excellent as it is in a good central location. As for the type of holiday it would provide, i would say it would appeal to couples looking for a relaxing holiday and people who want a quiet base but who want to get out and about to explore the island. For families with active children or teenagers, i would strongly recommend Lassi or Skala as there would be more to occupy them in those resorts. 8-)
