We spent 2 days in Nikolas's house in the center of Plaka in september. Firstable, the place was exaclty the same as the pictures we saw in is page and even better. It's huge, everything is clean and decorated with taste.
We cannot believe find a place like this in the center of Plaka, around all shops and restaurants... We were two and we enjoyed the breakfast on the balcony just over the commercial street, and also have a drink on the rooftop with the greek melodies from the street. Even if the street is animated, the rooms are quite for sleep... Nikolas is a nice host, we contacted him the day before, and received an answer 20min later, i helped us to find a taxi and to discover the district. I recommended this place for everyone!
