The room was clean, and big!
The bed was big enough, there was a desk and a couch in the room.
I didn't meet Charlotte but I've met her flatmate Lili who was helpful and kind.
Also Charlotte left me the underground map and some advices.
There is a Sainsbury just across the street and Westfield is 10 walk from the house, so really great location!
Besides there is a 24 hours bus which takes you to Piccadilly Circus just at the end of the street.
I'll definitely come back :)
