We had a very pleasant stay at Mark's house. Mark was there to welcome us and explain everything. The house was very comfortable, well equiped and spacious for us, a family with three teenage kids. Much better than 2 hotelrooms which we would normally have had. The beds were exceptionally good. The wifi was perfect (the kids asked me to mention this ;-)). The neighbourhood is quiet; the house in a very 'British' street. Access to London is perfect: a 30 min ride by train brings you into the city centre. With the tickets you can travel also for free on the tube, the bus and with a discount on the Thames boats.
