Hi,
I've found a place in BKK1 for $300 a month - it's two-bed so it'd be great to find a roommate so we could split the cost 1/2.
I'm 23, from the UK and will be here for a few months on an internship. The landlady is really nice and helpful, and it's close to the monument and some nice cafes etc.
It has a small kitchen, living area and bathroom and the rooms are nice enough. There's no internet but you can buy a 'dongle' for $20 and use it anywhere, I'm told, and for the price of the apartment I guess that amount is offset anyway.
Get in touch if you're interested in sharing the place!
Cheers,
Josh
