The location of Stefanos's place is incredible. It is located above the old town, with a spectacular view of the harbour from the big balcony. We spent a lot of time out there, it was a big highlight. The location is also very quiet at night due to the fact that it is removed from the town itself. But don't worry, the town is literally a 5 minute walk down a (steep) hill.
The apartment itself is clean and spacious, and has all the amenities that you could possibly need. The beds and pillows were very comfortable.
We didn't meet Stefanos, but his communication was great. He would respond quickly to any inquiries. Stefanos's parents run the place, and live in a separate apartment in case you should need anything.
Ensure you arrange (free) airport transfer to and from the airport in advance with Stefanos and/or his father, especially if you have a late flight. Taxis are not really an option because of the location.
