Great experience with Yannis and his apartment! We easily arranged for a transfer from and to the airport through Yannis, which made navigating a foreign city much less intimidating (he was also able to facilitate obtaining pre-paid SIM cards which was very helpful). The apartment is located in a residential neighborhood with nearby cafes and restaurants--I felt very safe walking around. It is about a 20-30 minute walk to the Acropolis, which was also convenient. The apartment itself is spacious and modern. It is also well-stocked with amenities needed for travel (soap, shampoo, washing machine, wifi, maps). I definitely recommend Yannis and his apartment to anyone planning a trip to Athens!
