Grit's house is light-filled and comfortable. It's in a gated complex; there aren't too many grocery stores nearby but there is a McDonald's right outside and you can walk to the lovely Roman Road market.
Bow is some distance out of town but if if you're comfortable with London buses, then you'll have no trouble - there's a bus down the Bow Road every few minutes to the Central or the Hammersmith & City / District lines. The DLR is quite close which gets you easily to London City Airport.
Getting in was a breeze. I was able to do laundry as well, and got to my appointments in the City easily. Grit was very helpful throughout!
