We had a pleasant stay in a well equipped flat in central Athens. Eleni was also accommodating and let us check out a little later as the next guest had their flight delayed.
The only thing to note though is the flat faces a Main Street so it can get quite noisy in the living room where the sofa bed is. The first morning, we heard drilling from some building works across the road and on our third night, there was a party that went on till past midnight.
Otherwise we really enjoyed our stay and would highly recommend it to others!
