As per the ad, the area is fine and it is central in the new sense of not being near the west end but still interesting and lively. Kind of TriBeca.
Too busy for me but I’d be in different mode as a tourist so I’m sure you’ll like it 
Fwiw, I still think Greenwich is a pretty good choice for a multi-generational family gig; aside from Cutty Sark the tube into the centre is very fast, the old Naval Academy buildings, the market, the Meridian, great range of little local eateries, fab open spaces, etc. It’s great to walk around as well as there is plenty of 18th century housing stock remaining with historic associations.
I also quite like the foot tunnel under the Thames to Docklands - still got a crack in it from a German WW bomb
But sure, understand how Shoreditch works.
