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 > Locations, select the location, then click edit
2. Add all the directions and information you need and click save
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?
