We stay 3 days in the apartment and it was perfect for what we looked for. The apartment is just like in the photos. Location is amazing! Is closed to the acropolis and all the things you must do and go in Athens. We dont have to take a bus or metro at all.
We did not met Leonidas but Chris picked up us in the airport and gave all the recomendations we need, things to do, information about the city, where to eat, etc. Also in the apartment there is a lot of information about attractions, museums, tickets, etc.
It was a really good experience. We recommend Leonidas!
