We had a great stay in this flat with our 2 kids. Great shower, clean and comfortable bed and sheets, and the kids managed sharing the couch to sleep, but having an extra matress would really be a great addition to sleep 4 more comfortably. It is close to buses and about 10 minutes to an underground station, and the hosts are very prompt to answer messages. We got a heat wave, so we missed not having air conditioning, but I believe this is not normally an issue in London. Most windows flap open, but they are a bit difficult to manage. Also, squirrels did show up once right at the breakfast table, through the open windows. This was probably because of the scaffolding around the building, which I believe is coming down soon. Also, the lift was out of service for half of our days there, there are a lot of stairs (5th floor)! Finally, the key must be taken and returned at a nearby shop, where there are souvenires, drinks and they can also add credit to oyster cards, which was convenient. Overall, I'd recommend this flat.
