The very first time I ever visited Tallinn, Estonia, about 20 years ago back in the early '90s, I stayed in the Hotel Viru. It was a memorably bad experience. My bed was a straw-stuffed pallet placed on top of cinder blocks, and that was the highlight. I stayed in the Hotel Viru again, many years later, and had a much more pleasant experience.
On my first visit there, our Estonian (though ethnic Russian) hosts warned us about the bugging of the Hotel Viru – apparently it was well-known amongst the locals. Now 20 years later, here I am reading about it in the Smithsonian Magazine!
