I am using Hosted SharePoint with Apps4rent for quite some time now. I initially signed up for Hosted SharePoint 2010 and got it upgraded to SharePoint 2013. The transition to SharePoint 2013 was seamless and they support team made it very easy for me. Their ability to provide 24x7 support is commendable and the support team is always polite and they know there stuff quite well.
The pricing is very good and best I have seen so far. The control panel is good even a non technical person like me can use it without any issues.
