Great location for seeing all the sites in central Athens, and lots of good dining options nearby. The apartment was very clean and spacious, and the AC units in each room make it easy for each guest to set the temperature they need.
Nikolaos responded quickly when I had questions and at one point the elevator in the building was stuck and he came to get it fixed straightaway. He was also very accommodating in letting us have an early check-in and late check-out as it was feasible on our dates.
I had to give four stars only because we had a problem at check-in with having the wrong code for the lockbox or Nikolaos was supposed to meet us but was not there. He came as soon as he could when we called, but we really wanted to get into the place right away after an overnight flight. He was very apologetic about the situation.
But overall it was a great stay and I recommend the place for anyone wanting to visit Athens.
