Dimitris's place is just wonderful! The apartment is quite small, but well-equipped and comfy. However, the stunning part of it is the balcony which is 3 or 4 times bigger than the apartment itself! The views are a real delight!
Every place you'd like to go to in Athens (Acropolis, the area around Monastiraki metro station with its numerous restaurants, Plaka and so on and so forth) is at a walkable distance, as walking around Athens is a real pleasure with those very pleasant temperatures and lots of streets with orange trees and beautiful houses).
At the end of the day, Dimitris's place was the perfect place to have a rest. Totally recommend it! :)
P.S.: This guy really likes hospitality and you'll surely discover it yourself.
