Location, location, location. In this case, excellent, especially if you intend to use the Underground. Literally next door to the Old Naval College, and readily accessible to both a bus stop and the DLR. (It would not work as well if you intend to take a taxi into central London each day, however.) Cozy bedroom. Short walk to local restaurants, grocery, and laundromat, as well as the Maritime Museum and Observatory. Patrick is a very gracious host; among other things, he showed me how to prepare a proper English tea.
