We enjoyed our stay very much. Panos was very helpful and gave us a lot of good recommendations. If there were any issues he always took care of it right away. The house has a very authentic charm, especially the terrace. You shouldn't have any problems with walking a few stairs, because its more on the upper floor, but the view is worth it. The bus stop is about 5-10 minutes walk away and from there you can go easily to Fira/Oia/Perissa. If you enjoy staying away from the touristic life and the grouded streets, its a good place to be.
We were very happy with our stay and would come back any time.
