We stayed at Stefanos' place for a week and it was absolutely wonderful. The flat is very clean and has everything you could possibly need – even a moka for morning coffee! The building also has a rooftop (the view is alright, not amazing, but still very nice). The location is also perfect – you will be able to explore the hidden and more local (especially food) gems within Keramikos whilst still being within 10-15 minutes walk from the historical city centre. Stefanos was always available and ready to help and answer all our questions. A lovely and very enjoyable stay overall!
