This unique hotel is in fact prison built by Tsar Nicholas in 1837. You'll be happy to hear that today there are no window bars here. Or that you can shorten your stay! On top of that 5 priests blessed the building in 2002, and removed all the negative energy from the former inhabitants - so you can now enjoy comforts of boutique prison cells.
Walls here are one-metre thick and windows are triple-glazed, which creates a very calm atmosphere. You can also dine in suprisingly nice restaurant, or relax in finnish sauna. Guilty!More details on booking.com
