The location in the heart of the old town a few steps from the lake, but THAT'S IT!
False advertising announcing non-existent balconies and lake views. The lack of insulation both from a visual point of view (room overlooking the staircase of the building without even a shutter), and from a sound point of view (you live with the neighbors, but also with the noise from the parking lot and the trash cans right under your window).
