This is a very well located place for walking in Sifnos. Several of the walking trails leave pretty much from the door of Aristidis's place. The walking is wonderful. The apartment is one of six, perched over the sea and at the entrance to Kastro, a really beautiful village. The village is great to explore. There is a small port at the bottom of the village with fine swimming. We didn't rent a car and between swimming, walking and enjoying the few restaurants/tavernas, we had a very nice stay. The room is clean, and well designed and shares a veranda overlooking the sea. Check in was easy and friendly. The only small issue is that the room lacks privacy - if you want it. The front door opens directly onto the entrance of the room next to it and the shuttered French doors that open onto the sea view mean that when open, anyone can pretty much see right into the room - and you have to have the doors open to get air flow and view. (There is an air conditioner but we didn't use it). We didn't find this too much of an issue but if you do want privacy, then the doors will be shuttered and the room dark. All up, Aristidis's place is good value, well located and the Kastro village is very beautiful.
