Hi Sandra,
You'll never guess over I'm writing this email from a cave! We're on holiday in Spain now. We spent a few days in Barcelona first. It's a great place but we had a good time though I didn't feel well one day. Anyway, after we left Barcelona, we come to spend several days in Granada. And guess what? We couldn't find a hotel because there were quite a lot of tourist. Then someone said, “Why not trying the cave dwellings（住宅）here?” We thought he was joking, but here we were really in a cave dwelling and it's wonderfully. Tomorrow we're going to visit a palace in Granada. We've enjoying it very much that we don't want to leave this amazed place. We're never going to have enough time explore everything!
Take care!
Ben
