I find libraries immensely soothing and am lucky enough to have several nearby to rotate through so I have also done this.

Combining a cycle to get there and coming back with a new book in my laptop bag is a good feeling.

Video calls are tricky, since you don't want to disturb others. Audio calls can be an excuse to take a walk outside in the sunlight. But I generally try to plan around calls and make the trip when I want to focus.

I'm also happy with just a laptop, which not all developers are.

I also quite like the background noise of students doing homework and old people getting taught how to use computers and the other human life going on quietly in the background. The occasional group of toddlers having a sing-song is a special treat.

On video calls, the library I go to is in some kind of cultural center & community space mix. So there are some common spaces that you can talk, and a cafetaria. These alone solve my problems for quick un-planned video calls. For daily meetings or planned pair programming sessions, I also wait for the meeting then head over to library.
