We spent one week in Sofia's apartment with a friend.
The flat is like description, and very fresh, good point in summer I think.
The neighborhood is popular and at the beginning not safety. But in fact there's no problems with the neighbors.
The apartment is really closed to the metro station, about 5' min walk. It's perfect for visit Athens.
Sofia and his friend Christos were very reactive for communication and very helpful.
It's a very nice place for an airbnb traveler !
