We only stayed one night at the Olymp II so we didn't have time to use all the facilities but still some things stand out. 1) A large buffet breakfast with more variety than usual (somewhat weak on the vegetable side 2) A big room with a nice balcony 3) good location close to the beach 4) quiet neighborhood. The staff was welcoming but were rather strict on the administrative side, both passes had to be shown (none in Sopot). Not all speak English though, mine was German speaking which is fine by me.
It should be noted that a large proportion of the guests are German pensioners.
The room cost was low, around 350 zloty.More
