On a recent business trip to Poland. I had to take the Art hotel as my second choice. What a piece of luck that was!
The hotel is not modern but more boutique. It has a friendly feel and the staff make you feel so welcome there was no issue that they would not try and resolve.
The location is ideal for the old town which really is the heart of the city. With bars a plenty to sit back and relax. The room itself had a bespoke feel with all the amenities that would make your stay more than comfortable.
If you want to keep away from the new/modern hotels than stay here
This really is a little gem enjoy!
