We spent 2 rainy days here. We had a few other things to do around Varese, but back at the resort, the spa was very welcoming. There weren't too many people, so we basically had the indoor pool to ourselves. There was also a nice Turkish bath, sauna, jacuzzi, etc, so we had plenty to do. I had a beautiful massage the second day.
One negative thing, it was between seasons and the heat was still on, so the room was warm. We asked the front desk to turn off the fan and we left the balcony door open and we slept fine.
Unfortunately, I didn't get to try the restaurant for dinner or lunch, but the menu looked amazing.
We will definitely return when in the area.
