Bangkok booking

I've been asking people who have been to Thailand for a recommendation on a place to stay in Bangkok for the first night I arrive, but haven't found any good leads yet.

I searched hostelworld.com but their ratings are quite confusing when you have like 300 places to choose from and so I'm really unsure still of what to pick.

I need to book 1 night ahead of time because I am arriving in Thailand around 10:30pm at night the first night, and so won't have enough time to look around and find something that I like.
