Really amazing spot, its in a quite neighborhood and has a Boris bike point around the corner. The flat is easily accessed from Stanstead (get the A9 and get off at White-chapel its a pleasant walk through markets to Shadwell)

The flat is a 5 - 10 minute cycle to Tower Bridge and a 5 minute walk to the DLR which within one station accesses the entire city through Bank Subway station.

Bed is fantastic and shower has to be experienced... rain shower in a wet room... Luxury!

The patio is also great (though we spent all our time in the City Centre), the barrista coffee machine is a nice touch and the decoration of the flat makes it a really cool place to be in. All this and there are genuine working markets just to the north toward White chapel making the walk to the flat nice if coming from Stanstead).

My advice for london ...

-Get an oyster card as you arrive in the city.
-Understand the 'Boris Bikes' arrangement before getting there (and the cycling rules).
-Pick a few things to see, London is expansive and while wandering can be very cool, indecision will eat up your time.
-The comedy clubs and TKTS stand in Trafalgar are well worth a look.

My advice for the flat...

-Get in early while its still cheap.
