Lovely hotels and enjoyed it. However we paid for a room upgrade but not 100% we received what we paid for, try speaking to staff about it but got nowhere.
Room was nice and bed was comfy, the only issue we had was that our spare room card and remote was taken from our room, which worried us but staff didn’t think it was major. When we came back one afternoon our balcony door was left open, we was taking this a human error but did worry us. If we wasn’t so high up I would be stressing. Bar at the hotel is extremely pricey compared to majority of Warsaw.
