I am about to buy train tickets for the Trans-Mongolian railway. The Express to Russia website is really easy to use and the staff seem helpful, but I'm a little cautious because noone on the forums seems to have used them before and I can't find reviews elsewhere. I know they are helpful and the prices are good, it just seems too good to be true - is there a catch? Has anyone bought train tickets from them before?
I know this has been asked before but the posts are a few years old so I was wondering whether anyone had used them since!
