Firstly: the view! From every window in the flat and from all the terrace you have amazing views: full view to the Acropolis, view over the Ancient Agora, the hills around or over all Athens.
Secondly: the terrace! Spacious & nicely decorated with plants. Unfortunately it was heavily raining the days we were there, but in summer it will be tempting to sleep in the also spacious Pergola in the terrace which is somehow an addition room seperate to the flat.
The host: very easy and helpful communication with Dimitris. Due to his schedule, it was Dimitris' father who "received" us. He welcomed us very warmly, and explained us everyhthing needed to know about the flat and the neighborhood.
