I'm always puzzled by the rumour that C# is in a scary bit of London when it is actually in one of the poshest. Ursula Vaughan Williams used to live around the corner and Roy Guest was the actual next-door neighbour. There's a bus stop right outside for the 24-hour 274 which goes past any number of stations so there's no need to walk anywhere. If you've left your vehicle in Regent's Park free parking, it goes past theretoo. True, some people object to the 5-minute walk to Camden Town tube, most likely because this involves going down Parkway and realising that the jolly people spilling out of jollier venues have probably had a better time. You could always walk to the equidistant Chalk Farm instead.
