The place is amazing. Unfortunately I only spent one night at this beautiful apartment, but it would be definitely worth a longer stay. It is clean and well equipped and tastefully decorated but the best part is that you enjoy a stunning view over the city and the sea both from the living room as well as the balcony.
You are right at the top of the city. You will find shops, cafes and restaurants in your neighborhood but of course it is a steep walk up the hill if you go to the city center and sea. But a taxi drive is only 3-5 euros from the city.
Another big plus if you visit anytime between November and April, the apartment has proper heating which is not guaranteed always in Greece.
