Located on the outskirts of the old town, literally less than 5 minutes walking from the main street in the old town, is this absolutely wonderful hidden gem. It's actually quite hard to find, as it's not signed well and you have to get onto a fenced private property with a guard to reach the entrance, but once you get there, it's nice.
Staff is friendly and efficient. The room was clean, all amenities worked, I had sufficient power outlets to charge my equipment and most important: the bed was comfortable. And, a big advantage. the rooms were well isolated, so there was little noise from other rooms or outside.
The place is right next to public transport, has the old town and other places for restaurants, sightseeing and shopping nearby.
I visit Trojmiasto on a regular basis, and I will definitely consider staying here again next time.
