We were able to hear the pipes in the walls every time someone above us used the toilet (or water in general), and it was quite annoying, especially at night. Additionally, there were flies in our room despite the windows being closed, so not sure how they got in. We killed the ones we saw, but more kept appearing each day.
Make sure that if you do stay here, request that your room be cleaned daily when the reception asks you during check-in. We said no to daily cleaning, but assumed that our room would still be cleaned upon request. There is a sign that you can put up to request room cleaning (which we did), but our room was not cleaned once during our stay.
There is a communal gym in the hotel, but I can't speak to that since we did not use it.
The hotel was also very far away from the city center (around 40 min via public transport). The only pro was that it was relatively close to a train stop.
Overall, probably would not stay again.
