We were there about 13 years ago in June/July.
Drove from Munich to Lake Como. Stayed in Menaggio, right next (I mean right next) to the church in the heart of downtown (bells rang all day long, but we got used to it) in an apartment. It was a great location, we had two young kids at the time and definitely took our time as there were naps involved. We found the area relaxed and laid back.
We rented through these people:

We obviously had a car, which was difficult to park. Ended up finding a public spot, parking it and leaving it for the entirety of our stay. Perhaps if you have your own villa/house there will be parking on site. Took the ferry to Ravenna, Bellagio, Varenna, etc. Great food, friendly people and a memorable vacation. Cute town square which was very busy at night, and Menaggio was very walkable.
There is a swimming pool inside of a "resort" type thing and you pay an entry fee - you have to wear a cap to swim which was a different kind of thing for us Americans (they are 1Euro each so no big deal). There is also a public beach which was mostly unused (and free), but I will say even in the summer, the Lake is freezing. I think someone said "You can tell who's German, they are the only ones swimming." One note as Americans - the grocery store (and most shops) do close "for a break" maybe 1-3 every day. You'll need to plan around that. Or, take a nap as the Italians do
