Hallgreen is a ground floor apartment on an estate just outside Inverbervie. I know it says one bedroom, but it's a single large room. It has a kingsize bed and two single beds, so it sleeps four. There's one bathroom with a walk-in shower.
The place has a three star rating. It's clean and has what you need, but it's not high-end. The kitchenette is small but it's got the basics. The decor is a bit old-fashioned, but it's comfortable.
The beach at Inverbervie is about two minutes away in the car. It's a proper sandy beach. The town itself is small, just a few shops and a cafe. There's a pub about a mile away.
For days out, St Cyrus nature reserve is about a fifteen minute drive up the coast. It's good for a walk. Dunnottar Castle is spectacular and it's roughly half an hour south, near Stonehaven. Further afield, Aberdeen city centre is about forty minutes by car if you need shops or a cinema.
Facilities: there's parking right outside, the wifi works, and bedding and towels are included. It has a TV. No pets allowed.
