This hotel is very good value at an excellent price, in a terrific location. It is a block away from Piotrkowska, Europe's longest pedestrian mall (check out Ato Ramen at the other end, about a 25-minute walk).
I stayed in Room 1, which was very convenient, but which had very spotty internet connectivity. That was my one complaint about the place; everything else was just fine. The staff were apologetic and did their best to help me, but the problems were essentially beyond their control to fix.
