Had a wonderful stay with my mum and I here - the Fulham area which Rich & Ellie's place is in has many accessible amenities and I would say for anyone going to London for a holiday and staying in Rich&Ellie's place, it would be nice to reserve a day just to walk around the general area which the apartment is located in and just sightsee around the area too.
The only issue was the firestarter/lighter in the kitchen was not working very well but we were happy to buy a new one and replace it with the kitchen one, but other than that, the stay was pleasurable, enjoyable and we thoroughly enjoyed coming back to it at the end of a long day out.
A note to future Airbnb-ers that the Putney Bridge station located near the apartment doesn't have a lift, so do take note that carrying your luggage up and down it may be tiring and beyond the physical ability of some. Pushing the luggage the 7-10 mins there may also be slightly tiring.
