We didn't met by person, but it was not a problem because the messaging was perfect and very exhaustive about all the info we needed. Corey and Kelly's house is so nice and comfortable and cozy (we stayed in October) you can feel like your own home. The position is a little far from the centre and most touristic places of London (1 hour), but if you prefer to have a good place with a well working kitchen or a good bed to sleep, clean bathroom and good heating, before to go out and visit the city, it worths to stay there. Anyway London has a great working transport system and with the due time you can go wherever you want (also come back home in the night during the week, maybe with a double time trip, but it works!!). So i suggest to stay at Corey and Kelly's place, it is a very nice house! Instead if you just want to stay out all the day and don't need a kitchen or a good shower, try an hostel in the city centre.
