My practice in London Bridge (above) is on Borough High Street, a 5 minute walk from both London Bridge and Borough tube stations, and within easy reach of the City. The room is on the fourth floor - it's accessible by a lift, but there is not step-free access to the toilet.
My first-floor room in Honor Oak (pictured above) is just over a block from the station. It's a 12 minute direct train from London Bridge, and also on the Overground line between West Croydon and Highbury & Islington. There are several buses, and free parking all around. It's within easy reach of Peckham, Brockley, Forest Hill, Catford and East Dulwich.
