@Alexandra1278 This is a mega host: someone who hosts commerically, not as a side gig. He has many listings. Sometimes people have multiple listings for the same space that incorporate different options - i.e. more bedrooms, breakfast included, etc. As long as his calendars are set up correctly so he doesn't get double booked, it should not be an issue. He has hundreds of good reviews, so it depends on your comfort level with booking with this type of a host.
Personally, when I'm travelling, I like more of a personal experience: if I wanted cookie cutter, I would stay in a chain hotel. But if you like what he's offering, I don't see a specific issue with his profile and listings.
