We enjoyed our stay at Maria’s. it was a cozy little place nicely decorated in the style of the area. It was located towards the top of Kastro on a quiet little walkway where visitors wander through during the day. It’s extremely quiet at night. Kastro is a fascinating part of Sifnos to spend a few days. There are buses that regularly take you to other parts of the island if you do not have a car. We had everything we needed at Maria’s. For those whose have difficulty climbing stairs, beware there is a loft bed but it is very comfortable! I would fully recommend a stay at Maria’s. You are staying in a historic stone house with lots of atmosphere!
