Eleni's place is in a great location and within walking distance to the Acropolis, if you like walking. The surrounding areas have wonderful restaurants and shops and this was enjoyable as we did a lot of walking.
Niko was very helpful in answering our questions.
The apartment was very clean. I was happy to see that both the air-conditioning and wifi both well, as these were of utmost importance to me.
I highly recommend Eleni's place. It's suitable for 1-4 people and I would certainly stay at Eleni's place again!
