My practice in Kingston Upon Thames is 10-15 minutes walk from Kingston Town Centre, Kingston or Norbiton BR station or the central bus station. K1 and K4 buses pass the bottom of my road and buses 131, X26, K5,K3, K2 and K4 all stop on London Road, which is a short walk away.
There are some pay & display parking bays at my end of the crescent but there are also pay and display bays usually available in Winery Lane ( which is the road opposite, across Villiers Road).
Disabled access is easily arranged with some notice.
My practice in Swansea is in West Cross, on the borders of Norton village. Disabled access is available.
