For visitors wondering about location: the place was much better situated that I expected -- a 12-minute walk to the acropolis in one direction, mostly along a pedestrian path. It was also an easy walk to many restaurants, those in the immediate neighbourhood being a bit more touristy, with less good food, than those just over the railroad tracks, in Monastiraki and Psiri (contiguous neighbourhoods that are a bit gritty in places, but also offer good quality).
The apartment itself was also a surprise in that it had more character than I expected: the original 1950s marble sink in the kitchen, original cupboards throughout -- a sort of very well-maintained grandmother's flat, with new furnishings and bathrooms added. The eat-in kitchen was our favourite room, as there was a table with chairs we could all sit around and enjoy our breakfast ... which we bought at the excellent bakery just across the street!
