The place was in a good location, clean, but a little bit noisy. We faced some hot days (for London standards), and the windows were planned to avoid cold and noise, but they do not open completely, what is not good during summer. The internet was good, and we felt like home, being able to use all the house's facilities (kitchen, living room).
It was not very private because there were two other guests in the other room. Everyone uses the same toilet, and it is outside the bathroom. The overall experience was good.
