I had an amazing stay at Niko's apartment during my time in Athens, and Nikos is a truly fantastic host. He was very attentive and thoughtful, before, during and after my stay.
The place was clean, very well equipped and with lots of natural light, as it is on the 7th and top floor of the building. There is even a tiny terrace in the bedroom which gets direct sunlight in the afternoons that I enjoyed a few times. A bit small for a couple, but enough if your are travelling solo – definetively a plus.
The arrival (keys waiting at the grocery store downstairs) and departure were easy and straightforward. Close to Omonia Sq. and Metro, the location is incredibly central, as it is quite close to all places usually visited by travellers, 20-25 min walk max I would say. The area is probably not the fanciest, but shouldn't be a matter of concern. I lived in the same are of Athens for two years some time ago, and I can say that it is not unsafe or dangerous.
All in all, an amazing stay at Niko's apartment, and a listing I would definetively recomend. Great value for the money.
Σ'ευχαριστώ πολύ Νίκο!
