HI, Thanks for your question regarding the Coach House.
The harbour is the 'centre' of Porlock Weir, which is less than 1/4 mile from The Coach House. There are two restaurants (The Cafe and Miller's at the Anchor), a pub (all three are dog-friendly) and a range of individual shops such as tea rooms, Exmoor Glass, etc.
The postcode is TA24 8PA.
