> My tips would be: check if it mistakenly thinks you can't directly walk to the station or something.
no, it knows and will give a sensible route if you ask for walking directions to the station.

Dublin is far from a grid layout, and has serious problems with eastwest transport; there are a bunch of buses and a tram going east to west in the city center, and a few partial orbital routes in the outer suburbs, but going eastwest near but not actually in the center is a problem. They were supposed to launch a proper inner orbital bus route a few years ago, but it has dragged on; in particular it requires special buses, because double-deckers (Dublin Bus's fleet is otherwise entirely double decker) won't fit under the very old railway bridges to the east, and it requires some hard infra work around Heuston Station. But at this point they finally have the Special Buses in operation (there were a lot of teething problems) filling in on other routes, so not sure what the holdup is.
That said, given that it's 15 Google Map minutes walk from the station to office (10 minutes in reality; Google Maps assumes a quite slow walking pace), I'm not sure I'll bother with the orbital bus even if it ever launches.
(I always thought they could fix this rather neatly by building one of these over the canals: https://en.wikipedia.org/wiki/Wuppertal_Schwebebahn)
