Toni's place was great! We were traveling with one other couple, and this place was perfect for that. Modern, clean, and centrally located.
The apartment was a short walk to the Kerameikos neighborhood that had lots of fun restaurants and bars (non touristy, great priced local spots) and also near the Acropolis.
The apartment itself is gorgeous, new and modern, but the building itself is older. This didn't bother us, but as a heads up, the elevator did not work when we were there and the apartment is on the 3rd or 4th floor. Toni and his friends were great & extra communicative and accommodated us when we got in late from the ferry from Santorini. We would definitely recommend this apartment and will be back!
