Giammarco's place is a short bus or train journey away from both Canary Wharf and the City; I walked comfortably to Canary Wharf. An additional charge for linen and towels meant it wasn't quite as good value for money as it appears, but it's a friendly flat with plenty of space. I didn't meet Giammarco, but his sister was welcoming and made the stay very easy and straightforward.
