Antonia's place is very cozy and everything was exactly as depicted in the photos. Antonia and Stefanos were both very friendly and provided us with useful suggestions on what to do and see around the city + neighbourhood.
The location is within walking distance to the Acropolis and possibly other major tourist attractions as well (we just didn't stay in the city long enough to explore everything we'd like to see). Would recommend for anyone visiting Athens!
P.S. On the way (walking) towards the Acropolis, DO make a quick stop at Elias bakery near the Thissio (?) metro station. They serve delicious breads + patisserie AND the store opens 24 hours a day!! :)
