Hi KamalS -
I've stayed many times in Luzern, including early June. Never needed AC, except in Sept 2003 when there was a major heat wave. The Hotel Schiff, now closed, put me in an upper floor room with airflow from side to side through different windows, and it was OK.
Never tried late June. I don't know those hotels, personally.
If I were doing it, I'd take the chance.
Towns near the mountains tend to have built in "natural" AC, in that at night , cold air comes down the slopes and cools that kind of town. Luzern has some of that capability from Pilatus, but not a lot.
