Ari's place is even better than in pictures, the bed is comfy, you have your own bathroom, heating or AC and its really nice place to stay but i went in winter so everything was closed, literally a ghost town, so i guess that in summer is way much better, is really close from the black sand beach is that's what your looking for. Fira is not in a walking distance, even though the bus stop is like 50mts away but the last bus is like at 7pm so take that in consideration, and also the taxis are quite expensive. More than that. Everything was ok. Aris is very kind and pending of you once that you are there. :)
