We stayed in George's place for two months and had a great time. The space itself is spacious, clean and well laid-out, with a comfortable bed, decent wifi, and enough kitchen equipment to make your own meals. There is a large local food market on the next street up every Wednesday and a supermarket just across the road.
George is an organised, communicative and friendly host who lives nearby to the apartment. Whenever we had any questions he was very quick and helpful with his responses.
The city centre is approx 30 mins walk away, or the Metro station is about 8 mins. Kypseli (a thriving bar and restaurant area) is also within easy walking distance.
George's place was better and cheaper than lots of the other options we looked at and we will definitely be staying there again next time we're in town... thanks George!
