Sophia’s place is very close to the center and is located in Pangrati, a very cool local Greek area. You can discover Athens by foot or public transport or taxi. The flat has everything you need and it was very clean. The communication was perfect. Definitely the place to be. Kolonaki, the posh area is just 10 minutes walking. You can walk towards syntagma square and Monastiraki. Supermarkets are nearby but I would suggest you to eat around as the food is delicious
