"The location was great, the room was clean, and the staff were fine. The major issue was the room itself.
My room faced the nightclub across the street. If you get one of those rooms, you may have to deal with people outside the club hollering and yelling until around 2 a.m. I had to play rain sounds just to sleep.
In my opinion, those rooms are deeply flawed and should either come with a steep discount or a clear warning from the hotel before booking.
The staff were okay. They recommended a laundromat when I asked, but compared with similarly priced hotels I stayed at in Prague and Warsaw, the service was not especially friendly or helpful beyond the basics.
I would not recommend this place. It is easy to get around Kraków from here, but you are gambling with the possibility of being kept awake by nightclub noise. There are probably better options in Kraków without that risk."
