Boutique hotels, well-known 5-star properties or castles. Poland has what you need. Bored of standard accommodation? Try a tree house or let the room choose you as a guest! Yes, it is true; there are a lot of unique and amazing overnight places.
The venues are diverse as the hotels; from large conference centers to small tailor-made solutions. One of the best?
The Wieliczka salt mine for an underground meeting - absolutely mind blowing!
