We really enjoyed our stay at Oliver's flat! We stayed for 10 days. The flat was across the street from a underground station and the bus pass at his front door! During our time in London and even before when we were organizing our trip, Oliver gave us so much good tips about the transport, activities, nice place to eat, etc. he was always helpful and available for our questions. The room was small but clean and the bed comfortable. We slept really well. If you go to London, we really suggest that you book there!
