Squarespace is a simple solution for anyone to use. The one problem with Squarespace (in my opinion) is that is comes with a default subdomain and is located on Squarespace servers. This restricts how much control you actually have over your own site. While it is not free, it does have a free trial to give you time to ensure it is the perfect solution for your needs.
I have personal had someone use Squarespace and I was surprised at how much they really do restrict what you can do. Depending on what you need, this may be a deal breaker, or it could not affect you at all.
