We stayed with krystyna for five days in Athens. Even though we didn't really spoke the same language we had the feeling that krystynas flat is our second home. She is a very warm and lovely person and we would recommend everyone to stay with her. :) The place is very clean and in the center of Athens. :) Metro and supermarkets are very close and the coffee in the morning is for free. :) If you can stay with krystyna!
