First off....read as much as you can..it will only be to your benefit!
Now that I have confirmation of hotels for my next trip I can recommend some.
Not sure what you are looking for, but I like Nana hotel. It is in need of an update, but always a popular choice among many. It is right across from NEP(Nana Entertainment Plaza) which is nice and fun. I use Asiarooms.com to book a standard room that does not have a view, but works for me. Many options, but Sukhumvit area is probably what you want.
Good luck and have fun!
