I stayed 2 weeks in Giorgios' apartment and the place is great! Clean, big and with everything I needed (didn't use the strength training equipment, I am too weak XD )
Communication with Giorgos is very easy, didn't had the chance to meet him but maybe another time!
The location is also very good, close to a park and some nice bars and restaurants, a supermarket, a pharmacy and it is also close to the metro.
