not only that what was said above but you can for instance leave one pyramid on the cross road between the house and the Teleportal, so that way you can get your sleep and are able to use the teleportal to travel to other places.
Granted you can do the same with the teleporter in aleroth and sleep in your first digs but hey .. having a house to store stuff, sleep, and decorate if you want, just pyramid hop into the castle after Janus has left, and grab the food wine bottles nice plates plants etc, if you are that way inclined ofcourse <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
