Warsaw - Oki Doki
Avoid. I stayed there, and they not only completely ****** up with ordering a taxi, but the place was freezing in winter. And the guy working there overnight was sleeping (24 hour reception, my ass) in a side room on a dirty old mattress.
Poznan: Fusion
Be warned - at night, the entrance is down a dirty, reeking of **** alleyway, across from a strip club.
