This is a lovely central apartment, perfect for a short stay in Athens. The location is brilliant, all the historical sites are within walking distance. There were lots of nice restaurants/bars within walking distance also. Syntagma station is the closest metro station - you can get a direct metro to the airport from here, which was very useful! Furthermore, Kolonaki felt like quite a safe area of the city. The apartment is very nice and clean, and has everything you would need for your stay. We had a very simple self-check in, and the host provided us with lots of useful information about travelling to-from the airport. I would highly recommend this apartment for your stay in Athens!
