There were no air condition in the apartment as promised, which was the main reason we chose that apartment, as we travelled with two small kids. It was difficult to talk to someone about it, as everything was by email, as there were no receptionist besides in the middle of the day, when you’re out exploring the city.
The apartment lacked a few remedies like a dish cloth and dish towel in the kitchen, salt and relaxant for the dishwasher, salt/peber/etc in the kitchen as well.
Also beside the noise from all the boats floating up and down on the stream outside (which the kids loved to look at), it was a good and clean place to stay in Gdansk.
