My wife, daughter and myself traveled by car at the very beginning of January 2019. I booked cheapest room for 185 PLN/night. Pre-upgraded to a Park View 2-room suite. We were also given a welcome drink vouchers for us, free breakfast. Pool, jacuzzi and sauna on the 10th floor are all very nice.
Breakfast has very good selection, including Frederic Chopin Brut sparking wine, self-service fresh juice, cocked to order eggs including egg benedict, etc. We also used room service inspired by the upgrade. Decent burger, tasty salads. I'd certainly return when travelling through Lodz.
