My sister and I were staying at the Eleni's apartment for 3 nights in September, 2017. An apartment is located two blocks south from Acropolis. Everything in the apartment was exactly the way, it was described on the website - very clean and cozy, with comfortable bed and equipped kitchen. During our stay all the appliances worked perfectly well. Check-in was fast and easy (regardless the fact, that we arrived very late in the evening). We communicated with our host through the WhatsApp messaging. On the check-out date Eleni's son Mike allowed us to leave our luggage for extra two hours.
If you need to buy anything, there is a supermarket just one block down the same street. We did not use public transportation at all - we just walked. Only on the way back to the airport we took Metro (station Acropolis) instead of a taxi (we had plenty of time before our flight). If we are back to Athens, we would definitely stay at this place again. Thank you Eleni and Mike!
