Hi Megagray111,
Due to the central London location the hospital unfortunately does not have parking facilities.
There is a tube station around the corner to get there and if you could get your friend to pick you up once you’ve had your procedure that would be the most cost effective option.
Alternatively, if you wish to go by car there is an NCP carpark near by:

If you need anything else, please let me know.
Only two more sleeps now!
