I will upload the photos and write more, but now I need to go to sleep. This trip was amazing! We saw so many nice things with my friend in such a short time. We had some local adventures (meaning getting lost in a not so good neighborhood), ate delicious meals and cookies all the time, saw many beautiful buildings and met interesting people. Gdansk is definitely worth the visit!
This is the address of my Gdansk photo album on Facebook: https://www.facebook.com/media/set/?set=a.607842819285444.1073741847.276514799084916&type=1 . I am still sorting the photos, the album will reach its final form in couple of days.
