we had a really good experience at Yanis place. The apartment is very clean, it has a washer machine, refrigerator and some courtesy breads and water. The location os good since his apartment is about 5 min walking to the Tram and Metro stations which can leave you in Greece's main attractions in 5-10 minutes.
another plus is that there are many good, authentic and very affordable places to eat. Since he is located in a local area uou can get the local perspective of Athens. Yanis offers a service to pick and drop you from the airport which is very convenient.
our stay there was very pleasent, he is also a very polite and helpful man. we definately recommend his place.
it also has AC which is extremely handy in Athens.
Thank you Yannis!
