Gibson Apt is over at Rosecraddoc Manor, near Liskeard. It's one of the apartments in the main house there. You're up on the first floor.
It's for four people but it's one bedroom. That bedroom has a double bed and two single beds in it. There are two bathrooms, though, which is handy. It's a 3 Star place, so it's clean and comfortable without being flash.
The grounds are the big thing here. It's 38 acres with woods and a lake you can fish in. There's a tennis court too. You can just wander out the door. It's very quiet.
Liskeard town is two and a half miles away if you need shops. There's a leisure centre there with pools and all that. Bodmin Moor starts about four miles out. Good for walking. The Eden Project is about a twenty minute drive.
You've got the basics: a washing machine, TV, WiFi. Bedding is included but you need to bring your own towels. There's parking right there. No pets, sorry.
