Parking on Long Lane, TW19

At first, it was confusing to look for the driveway because there were 2 different house number in the instruction (the correct one is 205). I wasn't sure if I had to leave my car keys in case the space owner wants to start my car or if the car needs to be moved for some reasons. But I didn't have to leave my car keys. I left my car at the driveway for 17 days, communicated with the owner before I traveled (didn't meet him but he was friendly). The driveway was allocated specifically for my car so no obstruction to traffic or anything. So far, a good experience and I might consider parking here again should I need to travel long term in the future.
