My stay was overall fine.
I noted some points which can be improved: missing WC brush, missing safety box, missing room mini-bar, non-working conditioned air. Some of them are very easy to be solved, for some other a little more work could be required.
Positive points are location (5 minutes walk to Krakowskie Przedmiescie, other 5 minutes to Plac Litewski and other 5 to Stare Miasto), very near public transport stops, quiet area, availability of bar/restaurant, kind people, good wi-fi, good bed and Tv channels, proper cleaning.
Overall, I can advise a stay there
