For years, stories have been circulating about how one side of the first foreign owned and operated hotel in Tallinn during Soviet times was completely wired up so that the KGB could listen in on foreign and local guests' conversations. When the iron curtain finally fell, those staffing the room destroyed or took with them what they could and high-tailed it back to 'Mother Russia'. Now the room is open to the public and exists exactly the way they left it, including an ashtray and Soviet-era cigarette butts. Sokos also fixed up another adjacent room which serves as a kind of time-capsule to Soviet hotel history. The museum, albeit small, is certainly worth a visit for both tourists and locals alike. Tours must be booked in advance.
