We found Lynne's property very easily, just a 5 minute walk from Notting Hill Gate station. The property overlooks what seemed to be a fairly busy road, we were woken up a couple of times from traffic and sirens but absolutely nothing unbearable. The property was easy to find and access. Up 3 flights of stairs or the lift if you need it. All in all it was a clean and perfectly great place to stay for 2 nights.
If I was being really picky - we found the decor a little bare and outdated but certainly nothing unbearable. The TV in the living room was quite small (we stayed in one night after arriving quite late) but everything worked and we had no issues with getting hot water.
