Om Yim BKK
Good value, rooms at rear are very quiet. Everything works. Good WiFi signal, but almost unuseable in early evenings due to slow speed, so lack of capacity I believe (or some unsociable **** using bit torrent).
Convenient location next to BTS station, but a short walk to the gay bars.

Two Guys Pattaya
Good value. Was assigned a room in the adjacent building which was at the rear & very quiet. Moved to a room at the front in the main block after 2 nights. Larger room with better facilities. A little noisy due to passing motorcycles at all times of the night. Good WiFi at all times. Good food, very friendly management & staff. Convenient for Sunee Plaza.

Sundowners Paradise Complex Patong Beach, Pkuket
Good value budget accommodation, but with just a little bit more style. Rooms at front directly overlook the gogo bars, so good for "sightseeing", but are quite loud until the clubs close, due to music. Very quiet thereafter, due to no passing road traffic and DOUBLE GLAZING -a big plus point, which should be copied elsewhere. WiFi signal only works in parts of my room, but I can cope with this.
Simply glorious display of guys in black underwear outside BB Boy last night, but sadly I lacked the energy to make it across the road due to some dubious Thai food consumed in Pattaya the day before.
