We've just returned from a very enjoyable 4 night stay in this lovely hotel and I cant recommend it highly enough. The staff are extremely helpful and welcoming, the excellent breakfasts have a huge selection of both hot and cold food and the rooms / bathrooms are finished to a high standard. Our large room had a beautiful view of the castle and river, although we did pay extra to guarantee this.
It's an easy 10 minute walk into the centre of Kraków although, as an added bonus, the hotel has 4 bikes which can be hired free of charge.
Wouldn't hesitate to return, they made my husbands 50th birthday very memorable!
