Manuel V. Solo - 5/19/2026 Confirmed reviews ALL

I booked the offer on the website that said half-board with dinner buffet. for my surprise I was told that was only 1 option of food available. a cheap pub like area with a food of the day option. the price was clearly cheaper than what I paid on the combined price! when I said I dont eat fried food was told that there was no option to the fried pork thing they had. the pool looked dated and overcrowded! If you visit Gdansk there are better options in the center. I left one night earlier and moved to a hotel in the city to enjoy my stay.
