Well, this really depends on what you mean by 'see' (and I suppose what you mean by 'space' as well, but let's just assume the ISS is the benchmark). Pictures like that, afaik, are taken with camera lenses that look roughly like [1]. You definitely can't make out city blocks with just your eyes from the ISS.

  NASA actually has a very long history of using Nikon equipment.

I meant with the naked eye. With an appropriate telescope one can of course see a lot of detail (see Google Maps). And given how low the orbit of the ISS is I guess it's easier to see things from there than from an orbit where there isn't a rest of atmosphere that slows you down (yes, the ISS has to be regularly pushed by space farriers).
