Nikos, Irin and Alex are wonderful hosts. They invited me for a day out at the beach and lunch, which was extremely nice of them. Nikos also insisted to keep snack for me at home and he bought variety of them and very nice wine. I did not meet their friend Ageliki but we talked on the phone and she is super nice and helpful.
The apartment is renovated, very comfortable, and has all what one needs. Nikos also bought a new TV for me. I enjoyed the balkony in the morning and evening. Koukaki is one of my favorite areas in Athens. It is live, dynamic, lots of shops, restaurants and cafes. I stayed at Nikos' apartment for a month and I had all services around me including buses, metro, taxis, dry cleaning, supermarkets, cafes, clothes shops. There is also one of the best bakeries about 15 minutes walk called Takis. Also Nikos will tell you about a restaurant serves Greek food. Delicious food with variety every day. It is 5 minutes walk.
What you see in the pictures and discription is exactly what you get.
I will always stay at Nikos' apartment when I am in Athens.
