Air conditioning wasn't working great, leaving the bedroom sweltering hot on our first night. We set up a bed in the living room for the remainder of our stay which allowed us to have a more comfortable night as it was next to the fan.
However, Isola is a lovely, safe area to stay in. The accommodation was at a great location, close to metro station and only 2 stops from Duomo. It was also in a quiet area with minimal noise.
