We loved our stay at Marili. Marina and Giannis are great hosts and the setting is idyllic. It is a bit out of town, the walk in takes twenty minutes and worth noting there aren't really pavements.
Parosporos beach is very close and perfectly fine, although we preferred the smaller Delfini beach, which is almost as equally close.
Marina was very generous and brought us cake and vegetables and we sampled quite a lot of their delicious homemade rakomelo (spicy honey-flavoured raki)!
Definitely somewhere we would recommend.
