Hi
There’s a congestion charge which you pay online easy!
We parked at Clipstone Street, pre book online I paid about 13:50 for 8 hours.
It’s not the most glamourous , underground car park. It’s near , reasonable , the instructions are clear , they even send you a photo of the street view so you can find it.
I walked to the car after it was so near !
Recommend it. I booked through your parking space app.
