We are a family of 6 and the apartment was a perfect size for us. It was very very clean and functional. The hosts were very helpful and arranged a minivan to pick us up from The airport. They gave us restaurant recommendations and tips on the local beaches.
The apartment is approximately 20 minute walk from the Acropolis and Seven minutes to Agora. We walked everywhere but it is very easy to get a taxi in the city. I definitely recommend this apartment.
