Our one night stay at Konstantino's place was amazing!
Location: < 5 min walk from Syntagma Station. It is also just one street behind the main shopping street of Ermou (with your Zara, H&M, etc.), with amazing restaurants, cafes and bars around.
Host: Konstantino was a great host! Communication with him was great, and he accommodated to all our requests. We had a late flight out at 1am, but he kept all our luggage for us and met us again at 10pm at night for us to collect it. He gave us great food recommendations in the neighbourhood too.
Apartment: Clean, basic, simple. Exactly as in the photos :) I stayed on a Friday night, so it was a little noisy, but we got a good night's sleep nevertheless.
We'd definitely stay here again! :)
