C10 bus will take you to HOD. Sounds like you'll very close to me (just south of Waterloo Station), in which case it's a 40 minute walk or a bit of messing around changing tubes and walking. Bus is by far the best option.
Sweet Chantelle is close-ish
External Link/Members OnlyThe massage places on the cut at a bit crap, overpriced. You're better off walking to Fantasia on Charing Cross road if you're after a rub n tug.
Soho walk ups are all walkable distance in about half hour so that's a decent option if you've a spare afternoon and fancy getting out for a wander in Central too.
Then Bayswater / Marylebone / Baker St / Paddington is pretty easy to get too on the Bakerloo line from Lambeth North/Waterloo and where you'll find a wealth of AW talent.
Slightly more difficult to get to is East, but anyone around Liverpool St is easy enough on Waterloo and city line or bus, and a nice walk back along the south bank.
For punting the area is pretty sparse, but excellently located for transport to get pretty much anywhere zone's 1-2, and beyond if you don't mind a slightly longer journey.
