Location is close to the centre of Athens, in my opinion that's Syntagma square. It is located in Kolonaki, around 10 min walk to where all the cafe's and pubs are in the hip centre of Kolonaki, known for the high end shopping stores, pubs and cafe's as well as a quite residential neighbourhood. Also short 3 min walk to the American Embassy and roughly 5 min walk to Megaro Moussikis metro station which connects you to airport and to most Athens main attractions like Syntagma, Monastiraki and Gazi (Kerameikos) same line, it's good to start discovering the city from them. For the rest Uber connects you to wherever you want to go and is pretty much efficient. Apartment is nicely designed (girls taste though☺) and spacious. The rate I paid is definitely more than fair and I would say cheaper than actual value. What I loved the most is Martini's cafe, a block away, where I had most of my breakfasts, afternoon coffees, with Ben and Jerry ice cream to go, and I have to admit, very cheap.
