Communicating with Stavros is very easy, he responds fast. The apartment is not in the centre itself (Acropolis) but very near to the centre. One metro station away, probably 15-20 mins walk (we bought the 5-day ticket for metro/tram/bus). It is extremely clean and very practical. Stavors thought about everything that the guests might need. Lots of space and can have privacy by choosing to stay in separate room. The bed is very comfortable, the WIFI is working well, bathroom not cramped, tiny but practical kitchen and aircon/heater. There are bakery, supermarket, deli shops and two good restaurants in the neighborhood, not to mention the 24-hour fresh milk vending machine across the building. Stavros left some food items for breakfast. That was very thoughtful and kind. Will definitely recommend. And I can imagine staying there again.
