The Internet had a tendency to stop working despite full signal, but this was a really minor point. I'm only mentioning it so I can share the fix: just reset your machine's DNS servers. Mobile devices tend to do this automatically; on a Windows 8 laptop like mine, it's just a case of running the WiFi troubleshooter (right-click on the signal indicator in the task bar). My friend was using a Macbook, and wasn't sure how to do it on there, but I'm sure a bit of research and you'll have the issue sorted easy.
Absolutely everything about this B&B was brilliant. Top marks for breakfast, comfort, countryside location, ease of access to local restaurants, hospitality of staff, bathroom complementaries... Even a great selection of board games and a pool table.
