I'm right by Waterloo station.
Have tried the NHS search, but it doesn't say if the doctors are male or female (i would prefer a female) and I didn't find any recommandations for GPs in my area in the previous threads...
Your nearest surgery is probably the Waterloo Health Centre on Lower Marsh, which I believe is generally well-thought-of, but constrained by very small premises for the growth in demand it has experienced in recent years.
I use the Princess Street Practice (shortly to move - not quite sure where to). There are about 16 GPs who work there and you can always request a male/female.
I've always found them perfectly good but the downside of such a large practice is you never develop a relationship with a particular doctor if you only go once in a blue moon as they always seem to be coming and going.
Actually, thinking about it, not sure if they're accepting new patients - worth a call though - 020 7928 0253
I'd like to add a further vote for the Blackfriars Medical Practice. I registered with Waterloo Health Centre when I moved here and have had some less than satisfactory experiences with them. Blackfriars has been recommended to me by a number of people who are registered there - unfortunately they will not allow me to register as I already have a GP in the area.
