Parking on Highbury Road, LU3

No 1 Highbury Road, Luton I arrived at this space to find it was seemingly non existent. The street view on the booking showed No 2, rather than No 1, There were cars parked outside No 1 and I also saw a sign which said I needed a resident's permit to park. This has not been mentioned on the booking instructions. I called the space owner via the App and it went to voicemail twice. I then texted twice. No reply. I knocked on the door of No 1 and the lady who answered said she knew nothing about the booking. On the street view of the booking there was an marked space where I originally parked next to number 2. A resident then told me this was a turning space as opposed to a parking space and looking at the dead end road, I could see this was true. At this point I abandoned the space and found an alternative in Sainsbury's, Luton. Extremely disappointed and uncertain now if this was a genuine car parking space.
