This post contains some information and two samples of Bootstrap (modals) and Google maps. For both samples, stack overflow posts (below under resources) were of great assistance. I hope all these resources in one place will help someone else.

UPDATE :

November 5, 2013: A new post is available to demo Bootstrap 3 with Google Maps.

October 26, 2013: After fixing the demos from moving hosts, I realized that the below demos will not work for the latest version of bootstrap. There will be a new post with updated code. In the mean time, please be aware that bootstrap 2.X is required.
