Would appreciate advice on a trip for 5 nts in April

Going with a friend who hasn't been to NY. Only requirements are two beds in the room and mid-town or above. Between The London 2br for $800 and MO standard room for $550, which would you suggest? My friend isn't into shopping--other than a quick jaunt--I think she wants to spend most of the time doing things.

Other hotel suggestions in the price range $500-1000 would be appreciated.
