We spent 5 night with our family at the apartment and really enjoyed the stay.
Aris was very nice and helped us if we needed anything else (taxi, car rental, boat trip). The check in and communication was very easy.
The apartment consists of two separate "caves". These caves have no windows in the bedrooms, but are very cozy and cool at the same time. Outside the apartment you'll find a beautiful courtyard, where you'll have your breakfast and which is also a nice place to spend the evening for playing boardgames etc.
If you'd like to explore the island I recommend to rent a car :) !
