We had a wonderful stay! Helen is a kind host and the communication was very easy and comfortable. The apartment is very spacious, clean, beautiful and well-furnished. The sleeping room of the flat is very quiet although it's the center of Athens. The location is close to many restaurants, bars and cafés. Even the touristic highlights can be easily reached by foot or with the metro nearby (7min). We can highly recommend this place! We would certainly stay there again.
