Yiannis’s studio apartment is perfect. It is tastefully decorated and has everything needed for a stay, including a very comfortable bed and superb shower. The location is about 5/10 minutes’ walk to numerous tavernas and mini markets, whilst being far enough away to be quiet and peaceful.
And we had a lovely surprise on our first morning when Yiannis’s mother bought us some breakfast.
I would strongly recommend this accommodation.
As for Kos, there is lots to do - but definitely worth seeing Nisyros, Zia and the other mountain villages, and the salt lake (there were still a few flamingos there in September). There are so many good beaches, with the nearby Limionas and Agia Theologis well worth checking out, the latter being perfect for the sunset.
