Malbork Castle
Polonia Palace Hotel-Warsaw
Having personally stayed in this hotel several times I cannot recommend it highly enough.
One of the oldest hotels in the city it remarkably survived the Nazis destruction of the city in 1944 and was the only hotel left standing after the war.
It has a rich history having hosted many famous guests from Polish celebrities of the day to politicians and royalty.
Rooms are spacious, very comfortable and modern and if you request a room at the front of the hotel you will have a great view of the Palace of Culture.
