I have a small bee hotel which has been used for the last couple of
years by a number of solitary bees.

What is the best time to clean it? In other words, when is the interval
between hatching and the next deposit of eggs?

AIUI, after the individual eggs hatch, the larvae spend time feeding on
whatever food the female bee has provided, usually a little ball of
pollen and nectar, before pupating. They remain as pupae until the
following spring, when they work their way out into the big wide world.
So if you want to clean out the tubes to get rid of the old pupa cases
etc, keep a close eye on them in spring and see when the outer cap is
broken, then wait two or three weeks to make sure all the occupants have
hatched and flown, before reaming them out.

Many thanks.
