My fiancee and I stayed here for two nights in early May, and liked the place a lot.
The studio itself is clean and bright, and the bed was nice and comfortable. The pool outside is very well kept and was a lovely place to soak up the sun, which it gets for almost the whole day.
I only met Dimitris very briefly, but his family are very helpful, and have created a very friendly and relaxed atmosphere. His father Nicolas picked us up from the airport, and gave us our bearings on the island.
The area itself is quite quiet, which we liked. We had rented a car, so nowhere on the island was far away, but even so, there is a market, two good restaurants, and the bus stop to Fira all only a couple of minutes walk away. There's also a winery about a 15 minute walk away. It is quite close to the airport, but we didn't find the noise particularly disturbing, as the airport is not that busy, and with the windows closed, it's not very noticeable at all.
All in all, a very nice place to stay.
