Kavos studio is the best place to stay in Sifnos !
The studio is beautiful and really clean (like if you are in an hotel). The view of the room is amazing, in the bay of faros and the sunset is incredible from there. We really enjoyed the pool and the beach at walking distance from the studio. Fassolou is a beach with lot of fish and is more peaceful than the other beaches on the island.
Vasiliki and her sister are welcome and really friendly host, always available to discuss or to give you some tips.
And the plus is the yoga lesson in the evening with the sunset view! One of my best yoga lesson!
