We went to London 4 days, and we see a lot of thing, specially thank to Alessandro, He gave us a lot of good advice about the city.
The flat is really close to the victoria gare/station. You have to walk 5min to find the appartment et during theses 5 min you will find many store/cafe/restaurant.
The flat was very clean, the bed was a little to small but if it's for few day it's ok.

Good experience, I'll probably go back there
Thanks Alessandro
