We stayed in Monika's place for four nights, the apartment its well located, it has shops, bakeries and supermarkets around, and it is not far from city centre, only 10 minutes by bus.
The room is spacious, very comfortable, and clean, it has a big TV as well, the toilet was always clean and tidy, and the kitchen has everything you can need.
We didn't had the opportunity to meet Monika, but she was always communicating with us by mail, However we met her friend Kristina, which is a wonderful person, and very helpful.
We fully recommend this place if you come to Athens
