0 stars but you can't submit that. So...
An appalling car park where the machines rarely work and where you get fined while you try to get the machines to work. I stopped for 20 min trying to park using the machines and Ringo. In the end I had to give up and find another car park - Sydney Street is great. Same p[rice and reliable. I have been fined £60 for trying to park despite an appeal with evidence to this effect. Avoid this car park! It's not even worth a star at all.
