I like that I can create different schedulers for different things. It's easy to use on both ends, mine and the candidates that access it. I've never had an issue with it.

You can shape the appointment schedule so it directly fits your needs, due to all the functionalities. It can be an open schedule or protected by creating personal accounts. It speaks quite for itself and is easy to use. However, when you get stuck or are not quite sure how to arrange the schedule, they have the best support. Never I've recieved such quick answeres, friendly as well as helpfull.

SuperSaaS allows you to simply book meeting rooms and have visibility into what rooms are available for the day/week. No unecessary bells and whistles.
