Olive Logie: Wonderful rambling park, like a trip to the country in the middle of London! Check out the ladies bathing pond (if you're a lady!) in summer for a lovely secluded sunbathing spot & refreshing dip!
Olive Logie: A lovely bookstore - this Waterstones doesn't feel like a big chain bookstore. The staff are friendly, great recommendations and layout. I always buy more than intended!
