Although there was a slight miscommunication regarding early check in, Andrew was readily available by email and fast in responding. Check-in was easy and instructions were very detailed.
The location is quiet, and the house is well maintained and well stocked with the described amenities, perhaps the only small issue was that laundry powder/detergent wasn't provided. But there were a lot of convenience stores available nearby including tesco's and sainbury's so it was easy getting necessities and food.
There is also an approachable and helpful caretaker/concierge during weekdays that can help with receiving parcels/mails if you are out.
Will definitely look out for Andrew's place for accommodations again if I'm back in that area of London in the future!
