The flat is just perfect :). Enough space for 2 people.
Private balcony to enjoy your morning coffee, great transportation links (tube, overground) to the city or any other part of London. If you prefer walking, the location could not be better - nice 15-20 min evening walk along the bank of river Thames will take you straight to Tower Bridge.
And the host Nancy is very kind and warm. Always approachable if needed and replies promptly.
