Nikol's place was very nice. The roof top deck is wonderfull, great views at sunset.
We had never been to Sifnos, and it seems it is one of the less visited islands in Greece (even by Greek tourists). We were pleasantly surprised. The location of Nikol's place is great, walking distance to the beach and several restaurants. Unfortunately our schedule only allowed a one night stay at her place. While her place does have air conditioning, it does not have unit in the smaller of the two bedrooms. It was still a very comfortable stay. Just something to know if you are there during a very hot time of year.
