Try having a look here. You have more accommodation options than you can probably handle.

You can sort by location , star rating, last minute or year round discounts and name.

Hotels can be good value as the prices are per room, not per bed like a hostel. Paperwork, bonds, and viewing apartments on the ground is a possibility, but I’d rather spend time enjoying the place rather than hunting for places when i arrived - just my thoughts.

For other Thailand visits, have a look around at the other places on offer here:

If you wanna stay for more than a month, it’s best to rent a service apartment. It’s much cheaper than a hotel. Find one along Sukhumvit road.
Good hotels are not expensive too.
