Spent four nights in at Hotel Wawel which was excellent in every way.
Location is a short walk from all of the main attractions in Krakow, the castle, Jewish Quarter, Main Square in Old Town but still blissfully quiet. Tons of restaurants in the immediate vicinity. Only took us a 25min walk to and from the train station to get the airport shuttle.
Room was spacious and super clean. Bathrooms were also modern and very clean. No tea/coffee making facilities in the room but a free coffee/tea/hot chocolate machine on the first floor which was even better, delicious coffee.
The staff were very friendly, helpful and knowledgeable. They were attentive and assisted us in booking a couple of day excursions with hotel pick-up.
Breakfast was wonderful with pretty much anything you could want, and at convenient times for all (7-10).
Would stay here again without any hesitation in the future.
