I just updated extensively our Bangkok Hotels page here: http://www.davestravelcorner.com/articles/bangkok/bangkok-hotels-hostels-lodging.htm

I’ve personally stayed at most of these listed over the years – and reviews include the good and bad. Many of the hotels listed on this page do not come up in general searches for Bangkok accommodation in search engines. All range of accommodation is listed.

I Just stayed at S Suites Sukhumvit a few days ago – real nice addition – centrally located (seconds from the Asoke skytrain stop), friendly staff and a good restaurant.
