Angel Lane is a one-bedroom apartment on the first floor in central Alnwick. It's just for two people. The rating is 4 Star, which means it's comfortable and well-finished.
You're right in the town. The castle and the gardens are a few minutes' walk away. Barter Books, the big second-hand bookshop in the old station, is also very close. For a coffee or a meal, there are plenty of places on the main streets.
The kitchen has what you'd need, including a dishwasher. The bedroom has an en-suite shower room. There's a TV and WiFi. The patio is enclosed, which is handy if you bring a dog. Speaking of which, we don't accept pets, sorry.
If you want to get out of town, the coast at Alnmouth is about ten minutes by car. It's a nice spot for a walk along the estuary or the beach. For a longer drive, you've got the Simonside Hills to the west or the beaches up towards Bamburgh, which are about half an hour away.
