Cygnet Cottage is in Belford. It's a one bedroom place, sleeps two. It's got a three star rating, so it's tidy and has what you need but it's not high-end.
The bathroom is on the ground floor, which is handy. It's open plan living, so the kitchen and sitting area are together. There's a TV and WiFi. Bedding and towels are included. You can park on site.
There's a small patio garden for you. There's also a shared BBQ area in the courtyard with the other cottage.
You can bring dogs, up to three.
Belford has a pub, a few shops, and a supermarket about 400 yards away. There's a local museum and a farm shop at the top of the village.
For the coast, you're about a ten minute drive from places like Bamburgh. Budle Bay is nearby for watching wading birds. Holy Island is a short drive too, but you have to check the tide times for the causeway.
St Cuthbert's Cave is a few miles away for a walk. The local bus can take you to Seahouses or Beadnell if you don't want to drive.
Northumberland National Park is about half an hour inland if you fancy a change from the coast.
