My husband and I had lovely time in London. The room offered by Vanessa has all you need and it’s super close to one of the main stops of the Central line. You can also reach by walk many cool areas such as Brick Lane (and its market on Sunday).
Just keep in mind that you’ll stay in the apartment with Vanessa and her family, so, even though you have your own space and bathroom, they might stay up until late in the night and having, obviously, their own life, which it could be a bit noisy if you prefer to go sleeping earlier rather than later.
Other than that, we recommend to stay at Vanessa’s place! 😊
