Parking on St. Pauls Avenue, HA3

Parking easy to locate but we didn't park on the drive we parked on the street slightly blocking in the driveway of the owner but leaving enough room for their car to move. I felt as if I could have found on street parking on the road without the requirement to pay. Due to cars being parked on the otherside of the road it reduced the traffic to single lane so I was slightly concerned about my vehicle being clipped. Nevertheless, I was able to park and attend an event in London which gave me peace of mind and had no problems returning to the car. Property owner was friendly. Recommendation: property owner allows the use of driveway for just park bookings with their car (seemingly a small car) parking on the road in-front of the drive.
