BubbaWoo:
gdynia is the most modern of the 3 cities - shopping, bars restaurants etc. i dont think it is often described as a beautiful city - at least not on the scale of gdansk or sopot.
that said, there are a couple of places in there that are extremely pretty - gdynia orlowo is one of my favourites - a beautiful little bay with a river running out through the beach past the pier.
life is relatively convenient - more so if you have a car perhaps and want to shop at some of the larger stores out of town
Thanks for your introduction
