We did not meet Mark in person but he kindly arranged his friend to meet us. We received all instructions we needed and Mark responses were quick. His appartment is very convenient for visiting Wembley Stadion as well as very easily reachable from the Heathrow Airport. It was short way to the city centre too. House was quiet and location seems to be safe. Overall we enjoyed his comfortable and well equipped appartment (bed was very comfy but quite narrow for us). And our little one just loved his terrace/garden.
