I have never met so friendly and nice people as Tasos and Ruth! I enjoyed my weekend at Athens due to warm welcoming of these guys. Although the apartment is not that big, you will find all you need inside, even more than enough.
The location is perfect, you can get to majority of signs by foot. Also it's not a problem to find supermarkets, bars and restaurants around the place.
I highly recommend everyone to spend vacation in Ruth and Tasos' place.
