I highly recommend this place and Vassilis as a host; this is my best experience of renting an appartment so far and I don't think any other place can beat it.
First of all, the communication with the host was impeccable - I recieved prompt answers to all my questions prior to my arrival, and Vassilis and his co-host Hoho were very helpful and kind to us. Second, the choice of food provided to us was far above our expectations; it was so fresh and delicious that we were reluctant to go out for a meal and ended up eating mostly at home and we enjoyed every bite of it. Third, the place is very cosy, with an artistic touch, and with a lot of thought put in every detail. We especially appreciated the excellent guidebook which helped us to learn more about Athens and some money on tours. And, last, but not the least, it is located in a wonderful neighbourhood, which is very important in Athens, as some districts in this city are... a bit unpleasant, to say the least. So, we really appreciated that we stayed in a place were we could enjoy the singning of nightingales and other birds rather than traffic noise, and the cafes and shops around the appartment are wonderful (and good for people watching).
There are many more nice things that I can say about our stay, but then my review would be way too long. Just come to the place and see yourself how great it is!
