Doros is really very helpful and friendly, he immediately makes you feel wellcome and offers you all kind of facilities. His place is very clean and cozy, as if it were waiting for you to arrive and take possession. It is so sunny, that it is hard to start and leave, you'd rather spend the morning reading on the sofa and listening to music.
It is very central located, you can walk to most of the sites worth visiting and to the tavernas at the Exarchia area.
Don't hesitate to choose this place when visiting Athens!
