(Aimee=A Barton=B)
A: Hello?
B: Hi Aimee, it’s Barton here.
A: Hi Barton!   Nice to hear from you! Are you...
B: This is just a quick call, but Emily and I have just been talking about our summer holiday — we haven’t booked a place yet and we’ve left it a bit late.  We were just wondering if you know of any holiday rentals in your area — it’s so nice there.
A: Well yes, I can think of two or three places that are very nice — what dates have you got in mind?
B: The 10th of July to the 22nd of July.
A: Oh yes, that is quite soon isn’t it? Well there’s a place near here called Moonfleet...
B: Is that M-double O-N-F-L-double E-T?
A: That’s right. It’s quite a rural location, and it’s next to the owner’s house, but it’s got fields all around it, so it’s very pretty.
B: Mm. Sounds OK. Can you tell me a bit more about it?
A: Well it’s an annexe to the owner’s house, and it’s an apartment with two bedrooms and an open-plan living area.
B: Well I like the sound of it. Is there anything we might not like about it?
A: Well it’s quite a distance from the nearest shops, that’s all...
B: OK. And... well, I’ll tell Emily but I don’t think she’d mind that. Do you know how you book it?
A: You have to book on the internet. There’s a web address — it’s www.summer houses...
B: One word?
A: Yes... Then dot com. You’ll be able to look at a photograph on that.
B: OK. And what about the others? Where are they?
A: The second one I’m thinking of is called Kingfisher, and that’s even more rural. It’s a really beautiful location in fact, it’s by the river, and it’s got nice views — it overlooks woodland on the other side.
B: Is that an apartment?
A: No, it’s a three-bedroomed house. And that’s got a dining room as well as a separate living room and a kitchen. But I expect it’s more expensive. You’ll have to check the prices.
B: Mm. It’s probably a bit bigger than we need, but our nephew might be joining us, we’re not sure yet. How do you book Kingfisher?
A: You have to phone the owner directly. Shall I give you the number? I’ve got it here in my phone book... It’s o one seven five two, double six nine, two one eight.
B: Right...
