I'm traveling to thiland in November for 7 weeks this is my first time backpacking and I'm going solo would anyone no any good hostels where solo backpackers stay I'm 35 male from Ireland (KSR bit to mad for my first couple of nights)thanks
Asok near Sukhumvit is my favourite spot to stay in BKK. It's a perfect location for exploring the city, as it's on the Skytrain (BTS) and Metro (MRT). 'Interesting' nightlife around there (a different kind of mad than KSR). Plus there's Terminal 21 mall which has a super-cheap food hall on the top floor.
Asok Montri is a very decent hostel: http://www.asokmontrihostels.com/ A bit pricier than what you can find on KSR but worth it IMO. KSR isn't connected to any public transport apart from the riverboat, so you need to take taxis to get to places which aren't on the river, which is a pain with all the traffic.
That being said, I don't know too much about staying in other areas such as Silom, Chinatown etc. There are plenty of cool places to check out in Bangkok away from KSR!
There are lots of good hostels in Bangkok these days. For somewhere to meet other travelers away from KSR, I'd probably look to the Silom area. A lot up Sukhumvit way as well; personally I like the energy of Silom better. Lub d is one of the best / most popular... They have one location near Chong Nonsi BTS off Silom and another near Siam Square, both good central locations. Saphai Pae and HQ also good choices. Mile Map is another good one a bit further down Silom next to a big Hindu temple, near Charoen Krung Road which is a cool area to walk around. I checked out Asok Montri -- not a bad little place and certainly a lively area. But I'd suggest Lub d, though you'll probably want to book ahead as they're both often full.
