Martin is a very attentive and kind host! The flat is beautifully decorated and very comfortable - exactly as described in the listing! I was there for a month conducting research at The National Archives and British Library. Both are easily accessible via the Mile End stop, though the trip to Kew (TNA) is about an hour on the train. Central London is about 15-20 minutes on the District, Central or Hammersmith lines. It is a bit of a walk to the Mile End station from the flat, but there is a bus if you prefer (I did not use this at all). I recommend cutting through the very lovely Tower Hamlets Cemetery Park to make the walk more pleasant and a bit shorter.
There are plenty of grocery options within walking distance and the kitchen is fully equipped. I saved a lot of money by making dinner and packing lunches. I highly recommend this flat for working or pleasure trips!
Thanks for a lovely stay, Martin!
