Christos' place is really modern and fashionable, in a surprisingly quiet area of Athens within walking distance of some of city's best restaurants and bars, 5-10 mins walking distance to 2 metro stations, and we felt very safe walking around at night. We didn't actually get to meet Christos, but his friend Jason did a good job of making us feel welcome and comfortable. Would highly recommend for foodie couples/those who want to experience a relaxed side to city life.
