Most, if not all hosts let you have multiple websites, usually as part of their packages. That being said, I have used Dreamhost and NearlyFreeSpeech.net and found them both very easy to use. I would say NearlyFreeSpeech.net has a more straightforward control panel, but it's certainly not the type of hosting that would suit everyone.

I'm going to second Curtis's answer. I use Media Temple and find it to be perfect in that I don't need to think about it but can make changes easily when I do need to.

The reality is that for every good vote you'd get you'll also get someone that has had a bad experience. I currently use a Media Temple gs server for a number of sites, hosting my Git repo's, and development locations for client sites. I love it. I also know a number of people that have had issues with Media Temple and won't use it. For any of the popular hosts (Godaddy, MT, Dreamhost, Host Gator....) there are going to be people with votes for both.

Unfortunately that means you're going to have to try them out and see which one you like.

I'd use Dreamhost. It's reliable, fast, easy to manage your websites and you can install WordPress along with several other applications with one-click.

There are other web hosts that meet these standards, I'd take a look at a few more and see which ones work best for your current situation.
