Χρήστος was really a superhost !! He came to the metro station near the flat to meet us, then helped us to get into his wonderful studio ! All the equipment was provided as indicated, and even more ! We were so sad to stay only one night...
By the way, the studio is 10 min walk from the metro station, and Χρήστος can give you some tips for the local restaurants.
It was a real worthy place to be if you want to visit Athens for a few days, I would come again
