Doubletree, Krakow is excellent. The Polish staff are professional and efficient. It's a tram away from the Old Town (reviewers complaining of the distance are either ignorant, lazy, or entitled). You can actually take a tram from two stops, which can get you pretty much to the major tourist areas such as Wawel Castle or even Podgorze where the Krakus Mound is located. Hilton includes a sauna, a 24-hour gym, and a really good breakfast with smoothies, desserts, and local Polish bread and honey. They surprisingly even served champagne one morning. Rooms are above standard and the hotel feels very new. During lean months (up to March), rooms are affordable but during conference months and high tourist season, Doubletree can get packed - with good reason. As expected, you get the Hilton chocolate chip cookie at check-in.
