1.

a. This website offers a unique service: instead of paying for a hotel room, you stay in a stranger's house for a small fee.

I would prefer to stay in a hotel if money allows. I don't trust strangers enough to spend the night at their place.

b. The first opportunity seems a lot more attractive, because of the nearby beach and great seaside view. It's also a little cheaper.
