Rose Cottage is in Rochester, which is in Northumberland near the Scottish border. It's a very old building, a bastle house from the 1580s. It was built to be a stronghold. It's inside Bremenium Roman Fort, so you can see bits of that history from the windows.
It sleeps four people in two bedrooms. There's one bathroom. It's a 3 Star place. That means it's comfortable and clean but simple. It's peaceful.
The stairs are steep and a bit narrow. It's just part of an old building like this. The walls are very thick.
You're right in the Northumberland National Park. It's a Dark Sky Park, so on a clear night the stars are incredible. No streetlights.
The garden is enclosed. There's a woodburning stove for heat, and a dishwasher and washing machine. Bedding and towels are included. Parking is right there. Sorry, no pets.
For things to do, Kielder Forest is about ten minutes away for walking or mountain biking. Hadrian's Wall is roughly half an hour south. The coast is a drive, but Alnwick Castle and the beaches around there make a good day out.
If you're planning visits, these sites are useful: Northumberland National Park, Northumberland Coast and Country, and English Heritage for Hadrian's Wall.
