Vasiliki is the most generous and kind-hearted host you will ever meet. She drove us to and from the ferry, brought us delicious home-made food, and gave us countless helpful tips on where to explore/hike/eat. She speaks fluent English and knows the island very well. Although our ferry arrived late evening, Vasiliki drove us to our studio.
The studio has a beautiful unobstructed view of Fassolou beach. It is located on a hill and away from other structures so it was very quiet. The beach was a mere 30 second walk away :) Everyday, our studio was cleaned inside and our patio swept.
During our 7-day stay, we took the bus (air conditioned and had very comfy seats) to get to the different towns on the island. It was very easy to travel this way. It cost 1.80 Euros per person and the bus schedule was easy to follow. You can also rent a car or a scooter to travel but inexperienced drivers may find the "way of driving" on the island to be imposing - very narrow roads, fast drivers, and people walking wherever they want.
Overall, the island of Sifnos is very relaxed and an excellent destination for travelers who want to avoid the crowds of tourists, love sandy beaches, and/or enjoy hiking mountains. Breathtaking views and beautiful island architecture can be seen from anywhere.
