The radio room and its historically accurate door sign "Zdes' Nichevo Nyet" (There Is Nothing Here) are brilliant. With its Cyrillic typewriters, fascinatingly clunky security equipment, and official paper-embossing stamps, it's seriously awesome. Bring your postcards with you and emboss them before mailing them out.
Feel free to linger over the wall displays in the upstairs lobby, marvelling over the eminently regrettable food and the hilariously retro Soviet-era advertising. This used to be Intourist territory, and it shows.
And, since it's one of the tallest buildings in Tallinn, there's also a fantastic set of views over the Old Town and down to the harbor.
After the hour-long tour, you get to go down into the hotel's bar, which has all kinds of nifty mementos on sale. The sepia-tinted postcard set is a real keeper, and a "There Is Nothing Here" sticker (in Russian) is a cool yet lightweight souvenir. We will neither confirm nor deny whether one is currently adorning our hard-case luggage.
Make sure you book days in advance from the hotel's reception, thoughthe tour fills up quickly. If you're desperate, though, there may be some no-shows and you might get lucky.
