My stay at Dimitris' was very good. The space was just as expected, but the view was even better. His apartment was very convenient to all the sights, many many cafés and restaurants (excellent, so much fun and good food!), the Metro and other public transportation. The space was clean and comfortable. Dimitri's dad met me outside their building and kindly invited me in, went through all the details and gave a warm welcome in general.

I would say that this space was comfortable for me by myself for the few days I was there. However, I'm not sure how comfortable 2 or more people would be for more than a night or two.
