Quality WordPress Web Hosting
I used to run a web hosting business so I know quality web hosting when I see it. And most web hosts are not qualified to host websites. The only two I can recommend are DreamHost and SiteGround. And yes, those are affiliate links.
DreamHost is good because they have very affordable plans which allow you to host a great number of websites on a single account. Their uptime is very good, which downtime being scheduled in advance.
SiteGround is extremely reliable with excellent uptime, fast server response and good customer service. It is a bit more expensive than other web hosts, but it is worth the extra money in my opinion.
