Hey, in my opinion Como is a treasure for traveling, I highly recommend visiting Bellagio, it is called the "Pearl of Lake Como", this charming city is located at the intersection of three branches of the lake. An incredibly beautiful place, with a beautiful embankment, a must-see! And from taxi services, in my personal experience, the most comfortable is GetTransfer
https://gettransfer.com/en/directions/italy/lake-como , they are wonderful guys, know their business, and can also tell you more about the city and its attractions. By the way, about significant places, I also highly recommend visiting Villa Melzi D'Eril, there are a lot of exotic plants and sculptures.
