Sometimes, GPS can't locate you precisely. Providing detailed directions, parking information, or noting any one-way streets unknown to Google can help your clients reach their appointments on time.
1. Go to Settings - Location, select the location, then click edit
2. Add all the directions and information you need and click done
You have now added extra directions, remember to save your changes.
Pro tip: Why not add a quick video tour(sped up) so that clients can see where to drive and/or walk once they've arrived at your location?
