Alexandros' apartment is in a perfect location in my favourite part of Athens, Just off Iroon Square in Psyri, surrounded by great restaurants and bars, and a short walk from Plaka and Monastiraki.
The flat is clean, spacious, and has a great balcony.
We didn't get to meet Alexandros but we had great communication with Denisa, who was very friendly and helpful.
On our second night we had a bit of a problem with the bed collapsing (!) but it was dealt with in a calm and friendly manner we were not made to feel in any way responsible.
The only thing we felt slightly lacking was that the kitchen was a bit under-stocked. It would have been nice if there was some sugar and olive oil, for instance - these are not things you want to buy for a 2-night stay. And it would have been good to have had a couple of coffee pods for the espresso machine for each morning - there were 2 for the first morning but we couldn't find a shop that sold them and didn't want to waste too much time searching.
But I will absolutely be happy to stay here on our next trip to Greece.
