Battersea Park is a great urban oasis and is not far for those of us who work in Westminster. It is pretty diverse with rolling bits, botanic garden like sections, ponds and it is on the Thames. Perfect for a lunchtime run, if you’re quick.
Would be a nice spot to live, particularly if you work on the Southbank or in Westminster. There is a lot of air traffic along the Thames, but I’m sure you would get used to it. Also, no tube.
