Vibrant and exciting
Krakow is perfect for a week away but perhaps not any longer. The city has lots happening, and can cater for both cultural days out as well as sunbathing by the pool. It's not a huge city, so filling more than seven days might be tricky. Everything is insanely cheap - you won't need more than £300 spending money for a week (works out to roughly 1500 PLN).
Insider Tip:The Harris Piano Jazz Bar in the market square is a real treat - check out for their free jam session evenings. They have a brilliant range of cocktails and mocktails, and the music is always brilliant. Some nights have an entry fee, but never too expensive. The Sioux bar and grill does amazing meat platters for hardly any cost at all. The Jewish Quarter is brilliant - well worth visiting for a day or two. For a spot of sunbathing, check out the Clepardia outdoor swimming pool - a short taxi ride away.
