Margarita's appartment is maybe the only one place that you'll find opened all year in Folegandros (almost everything is closed on the island at low season). We strongly recommend it! Margarita is a super nice person and she proposed to pick up / drop us at the port. We didn't need it in the end cause it's definitely better to rent a car if you want to visit Folegandros. Thanks to her also for the super reactivity and the quick answers to our questions!
