We really loved Nikolas place and Antiparos island.
The apartment is located in the old city (Kastro) near all the restaurants and clubs but in a very quiet area that allows you to relax at any time of the day, it is tastefully decorated and has very nice balcony where you can drink a beer at sunset time while caressing the cat.
I would certainly reccomend staying at Nikolas place and we really look forward to our next stay in Antiparos.
