The room is tiny and so is the bathroom. They are however ok if you are alone and you want to move by bus and on foot as I did.
If I had to suggest where to go in Folegandros, I would recommend Chora, since it is the crossword of all bus lines. Barbara’s place is in the middle of Chora. The bed, the mattress and the pillow were absolutely perfect for my back: I suffer from backache, so I do think that I am a little more reliable than other people about it.
I had a wonderful time in Folegandros and I suggest that you discover it walking.
