ドゥブロヴニク really is paradise. It doesn't have long sandy beaches with palm trees and coconuts but it does have the most amazing old city I have ever come across. The old city walls protect the ancient town, and it's full of marvelous little restaurants, shops and entertainment. You'll be walking around with a sore neck from taking in the grand and spectacular ancient buildings.
I would recomend a day trip to one of the islands just offshore. We went to one and found a hidden lake where we just sat in the sun and swam in the warm clear lake.
A perfect location for a couple of relaxing days in the sun.
ドゥブロヴニク is very pretty but there's no real backpacker scene. It's overrun with couples, families, European tour groups of senior citizens, the jet-set crowd, and the see-and-be-seen crowd. Prices are ridiculously expensive! The Old Town is gorgeous but I wouldn't stay here for any length of time.
ドゥブロヴニク is lovely but overpriced! Stay in Lapad area which is near Lapad beach and full of shops, bars, and not too pricey.
ドゥブロヴニク is sizzling and very pretty. I cannot find words to express my pleasure visiting that city ten days ago.
