Rose: I’d love to go abroad on holiday next spring. What do you think?
Jack: I’m not sure. When were you thinking? In April?
Rose: Maybe. We have two days off work for our national holiday. We could take off another three days and go for a week. We could even go for two!
Jack: No, not two. If I take all my holiday in April, I won’t be able to take a holiday in the summer.
Rose: Okay. One, then.
Jack: Where would you like to go?
Rose: Well, I looked at flights. There aren’t any flights to Greece until May, unfortunately. I’d like to go there. But we can fly to Spain quite cheaply.
Jack: That would be nice. Where would we stay? In a hotel?
Rose: I’m not sure. I don’t really like staying in hotels. But we could hire a cottage.
Jack: I don’t mind either. Is a cottage cheaper than a hotel?
Rose: It’s about the same. But I prefer staying in cottages. It’s more peaceful, and we can cook for ourselves.
Jack: Okay, well, that’s fine by me.
Rose: The problem is transport. You can get to the hotels easily from the airport. They are all in the town centre, and buses go there all the time. But the cottages are further away. We’d need to hire a car.
Jack: That’s fine. I don’t mind doing that. Why don’t you pick out a few cottages, and we’ll choose one?
Rose: I’ve done that already. I’ll show you on the computer. There’s this one - it’s actually an apartment. It’s inside an old palace in this beautiful historic village in the mountains. Isn’t it beautiful?
Jack: It’s quite expensive though. And it has 3 bedrooms. We don’t need that many.
Rose: I suppose not. Okay, what about this one? It’s up in the hills. Very quiet and peaceful. It has a lovely view, look. And it’s not too expensive.
Jack: That looks nice. It’s quite far from the town, but I don’t mind that.
Rose: Nor me. Or there’s this one. It’s a town house. It’s big and it looks lovely inside.
Jack: Does it have a garden?
Rose: No, and it might be noisy, because it’s so central.
Jack: I think I prefer that other one.
Rose: Me too. Shall I write and find out if it’s free?
Jack: Yes, do. If it is, we’ll book the flights.
