Help, I cant find Topside House!

Please note if using Google Maps please head past the marked location on Google, further down the hill for 200m to find the property. The accommodation is at Downside House, Bath Road, Downside, Shepton Mallet, BA4 4JL. If arriving from the Northern direction (Bath and Bristol) head south on the A37 and you will see a turning onto Bath Road B3136 signposted for Shepton Mallet. The property is the red and yellow house on the grassy triangle as you have turned onto Bath Road. If travelling from the Southern direction (Yeovil, Shaftesbury, Bournemouth) head past Shepton Mallet and as you enter Downside on the A37 you will see the red and yellow house on your left just past Bolters Lane.
