We absolutely loved our stay at Puro in Lodz.
The rooms are really modern, clean, and comfy and the lobby/bar/restaurant was also lovely, very spacious and nicely designed. The service was friendly and we were grateful to be able to check in early after an early flight, for a small charge. Breakfast was very nice with a good selection and reasonably priced. The location of the hotel was also really good, right opposite Manufaktura and easy to walk to the central streets.
We went onto Warsaw and Krakow after Lodz and were sad that we weren't booked into the Puro hotels there - next time we are in Poland, we will definitely try to stay at a Puro hotel!
