Stayed for one month for work-cation and absolutely enjoyed the life on the island. It can not be a better option. A fantastic view of the Marmara sea from the living room, bed room and the garden. Meals/Drinks in garden while looking at the sunrise and sunset was a bonus.
The hosts are very welcoming, and we sent a beautiful night together outside in their garden over open fire, looking at the full moon during our stay.
The island is much quieter than other princes islands, but plenty of cafes/restaurants. 10-15 mins walk to beaches, where I worked some afternoons in the sun in October!
Very easy to go and visit other island/Istanbul by ferries.
Its on the hill top - sometimes its discouraging me to leave the house......
