Let's start - hotel is NOT in Warsaw. So don't put in your navigation one of 3 streets with same name which are in Warsaw. Otwick is separate village outside Warsaw.
Room cleanliness and staff are actually not bad 8-9 out of 10, but still some thing don't works, like lamp and etc. Also sometimes cheap products used in bathroom, TV most Polish.
Not bad hotel, but some SMALL things ruin overall "wow" effect.
For this price - i would expect 10/10, but hotel fails to delivery that. Even staff can't put your ice-cream to freezer. Charging you for wrong amount, some small things don't works...
Overall rating without counting cost - 8 out of 10 (4 out of 5) stars
