London Marathon double room April 23rd

Due to my partner's injury, he has had to defer his place in the London marathon 2016 and now consequently we will no longer need the room we had booked in The 4* Westbridge Hotel on Saturday 23rd April.  It is a double room with breakfast included and is a 3 minute walk from the DLR rail station and about 5 miles from Greenwich so if anyone else is interested in saving the travelling time and energy and having somewhere to store your kit by staying in London the night before the race, then I'm just looking for face value of £109.
