We had some great days in Krystians appartment and recommend it to everyone, who want to have a quiet neighborhood but only ten minutes walk to the beach, which some really nice beach bars and two minutes to several shops and the tram. The flat was clean and you find everything you need.
We also didn't meet Krystian, but we stayed in contact with him via phone during our visit and he was really helpful.
The only thing we want to mentioned, the bed is quiet small and better for a couple or a single person as for two friends. ;)
