Great space and exactly what you need. I stayed for a different reason than most reading this (buying a place in the neighborhood), but this is for the out-of-towners:
1) cant have a better location than this, or a more accomodating host.
2) Easy walk to the Tower of London, Bridge and the River Thames. Quick transport to all the places in the city you want to see in just a few min.
3) Amazing dock life just outside.
4) you get amazing views from her windows/porch. Can see the skylines of Bank and Canary Wharf.
