Nestor took good care of preparing the apartment for us and regularly inquired about whether we needed anything. He came over to fix the boiler when something wasn't quite right with the settings which was very nice of him. His apartment offers all the necessities you would need for a pleasant and comfortable stay for a few days in Athens. It is within walking distance of Omonia and Victoria stations.
The neighborhood is quiet and fairly close to the most central part of Athens. It mostly feels safe though one might need to be more cautious if coming home very late and/or by oneself. Altogether a nice place, worth its price.
