Turnstone Malthouse is in the middle of Alnwick town. It's a first-floor apartment in an old malthouse building. You get there by stairs, or there's a lift if you need it.
It sleeps four. Two bedrooms, both with kingsize beds. Two bathrooms. It's got a 4 Star rating, so it's well-finished and comfortable. The living space is all open-plan: kitchen, dining, and sitting area together. It's a bright, practical layout.
The building has history, but the apartment itself is modern inside. Everything you'd need is there: WiFi, TV, dishwasher, washing machine. Parking is on site.
You're right in the town. Shops, pubs, and restaurants are literally two minutes' walk. The famous Alnwick Castle is a must-see. It's a proper castle and they used it for Hogwarts in the Harry Potter films. The Alnwick Garden is next door, with the big treehouse and the Grand Cascade water feature.
The coast is close. Alnmouth village and its beach are about four miles east, a ten-minute drive. For walking, you've got the Northumberland Coast Path straight from there. Inland, Rothbury and the Simonside Hills are about twenty minutes west.
