George's flat is a massive, impressive piece of Athens history. We were two families, with four adults and two children, and there were two bedrooms we never even touched. The ceilings are high and the features are original. It is a bit 'classic' in some of the amenities but you quickly get used to it. The location is very good for getting to all the sights, although it could be a bit ropey after hours or in some of the side streets nearby.
George himself was a hero -- very responsive when one of the AC units didn't work right, and he gave loads of helpful information to guide our stay. Three cheers for George!
