This place has a lot of European charm and style. It's located in a small town, walkable to a cafe, restaurant, two beachfronts, bakery, and vegetable stand - most of which close by 2pm daily. While you may not need a vehicle for your entire stay, it is highly recommend (almost a must) to have one for some time. It's not easy to bike around the hills of Syros, and the supermarket, other beachfronts, and restaurants are quite the walk away.
It's a great place for a relaxing vacation; however, I would warn guests that, if you are American, it may not meet your standards. The kitchen is quite tight on space, with very old pots/pans as well as a temperamental stovetop. During our stay, we had many many issues with the water heater in the bathroom - although the owner was incredibly nice and timely in trying to get things fixed which we appreciated. Finally, the living area has a tiny CRT television, which barely works (we could not get much on it) and two uncomfortable couches oddly situated on the sides of the dining area. In short, you will get a European cottage feel here more so than an American luxury feel. Choose wisely.
