Glur Central Pratunam 

I've been staying at Your Central Pratunam as a solo western tourist for a few days and I'll recommend it to you if you're looking for a well-priced hostel in the middle of Bangkok. They serve a breakfast from 8AM at no charge. The rooms are pretty quiet and air-conditioned. What I like about this hostel is that the beds are quite bigger, queen sized I think, compared to other hostels. There's a common area where you can sit and it's spacious. It's the area where you eat breakfast. They also provide a laundry machine and some facilities for drying. There's no drying machine unfortunately but the area is right outside so it's more than enough. Lastly, it's very close to the main areas in Bangkok like Central World and only a few mins walk to the closest station. There's a close by cafe right in front of the hostel as well before turning into it. I recommend it. Also, it's quiet despite being right on the road and in the middle of the city. That's because it's a bit inside on its own culdesac. Overall, it's a good, quiet, and well-priced hostel. I definitely recommend it if you're a so traveler.
