The location is absolutely perfect, few minutes walk from the main turistic spot. And from some good food shops, and restaurants . The consequence of the central location, if you have a light sleep, is that you could find the street a little bit noisy.
The flat is a real home, spacious with the charm of an ancient family appartment with old furniture (anyway the bed is good). The balcony is big enough to have breakfast or else for two people. Katerina was reactive and very helpful. Warmly recommended.
