Top of the range for localisation, we couldn't be more central. We were six and the flat still spacious. Kitchen and bathroom are modern and convenient. The big plus apart for localisation, is the possibility to leave the luggages at a restaurant (Denis' friends) wich is very convenient to start your London tour before the check-in, and the same for check-out. The only negative point is the noise, but the localisation erase it.
We won't hesitate to get in touch with Denis for our next London trip.
