Overall a great stay.
Pros: Without a doubt Vanessa was one of the warmest and most welcoming hosts I've stayed with. I felt comfortable from the moment I walked in and the reliable wifi/Netflix was a nice bonus.
Cons: A bit of a hike from Belsize Park Station if you're carrying heavy bags. Also my first impression of the neighborhood was it looked a bit rough, but after half a day it was clear it was actually quite safe and trouble is more likely to find you nearer Camden Town.
