Many thanks to my hosts for welcoming me - everything was just perfect!
The room was really nicely furnitured and had anything incl. free WiFi to provide comfort during the trip. Furthermore I received a lot of useful informations - turn-by-turn directions from different airports and train stations and back and also to the interesting points in London, details on the neighborhood the room is located in (by the way - absolutely worth seeing) and even details on restaurants and cafés including personal recommendations.
Though my trip was rather shot and packed with appointments, I hardly ever met someone who was so friendly and cared so much for his guests. I would recommend anyone to rent this room.
