Gonzo is correct Nana is a shit hole now and a pale shadow of its heyday 10+ years ago. I've also always prefered Cowboy and these days try and avoid the whole Sukhumvit soi 4 area if I can. Cowboy was excellent when I was there in november but not cheap, but then neither is Walking street. Dynasty Inn was very tired and overpriced for what it is years ago so unless its had an upgrade I'd give it a miss personally. If you really want to stay near Suk soi 4 look at a few of the advance booking sites such as thaihoteldiscounts.com or Agoda and see what deals they have on the likes of Aspen suites and Majestic Grande in soi 2 or the Dynasty Grande in soi 6.
