Toni's place is wonderful! It is very clean and spacious with everything you need for a comfortable stay.
The area itself is fantastic with shops, restaurants, bars, cafes and supermarkets all close by. The metro station is also just a stones throw away. It is a very safe area and the locals are super friendly! The Acropolis and it's museum is within walking distance and I loved exploring the surrounding areas.
I would definitely recommend Toni's apartment to anyone looking for a great stay in central Athens.
