Just in case somebody is looking for a really nice apartment to stay while visiting KRK. We spent a week in KRK with 10 friends in total and rented a very nice house. We stayed more than happy with our choice because 1) the house looks and is much better than in pictures on internet 2) the agency we did everything through was very forthcoming, friendly and kind 3) the owners of the house made us feel like guests and not strangers - helped with grill, showed us around and helped with everyhting else we could ask for.
Definitely a suggested place! You will not be sorry!
Find the house link on the agency website here: krk-info.com/Objekt_Municipality-KRK-City-KR…
Hope it helps and enjoy your time!
