Awesome Appartment! You get a whole floor all by yourself to live in, with space for up to 5 ppl with no problem. The kitchen is equipped with everything, there is a big dining room as well (or at least you could use it as one) and its clean as well. (hint: its no hotel, so you might find some older furniture and things like that, but its is by no means a problem. We had no problem going barefoot into the bathroom or around the house, the beds were allright, there were fresh towels and sheets and everthing)
There is a backyard to sit when the weather is allright.
Vasiliki wasnt there herself, but her mother was instead. She is very nice and even spoke german to our surprise :)
Location was good as well, you need around 10min to the subway and there are some bakeries and grocery stores nearby. There is a park right outside the house across the street and a couple of schools nearby. So at around 8 a.m., there will be some school kids running around. If you want to sleep untill noon, you might want to close the windows.
So we had a great stay there and can recommend this Appartment!
