First of all, Marco is a good guy and will treat you right. My flight arrived early, and I was jet-lagged and exhausted. Since he didn't have a guest before me, he let me check in early, which was really helpful.
Things that are important to me are comfort, location, and avoiding city and traffic noise (which is difficult in Amsterdam). Since AirBnb doesn't show the actual address, the thing to know is that the unit is astonishingly close to the Centraal Station, the city center, and the tourist action. Yet there is almost no street noise. There is neighbor/neighborhood noise, but after a couple of days, you feel like you're part of the neighborhood, too.
Because it was advertised as a studio apartment, I was assuming there was a kitchenette, which there isn't, although there is a refrigerator, coffee and teapots, and of course the faucet and sink in the bathroom. So in that regard the amenities are perhaps comparable to a hotel room, although hotel rooms typically cost much more. And unlike most hotel rooms, the studio has full windows on two opposite sides, and is airy and spacious.
It worked for me, and I wish Marco much success as international tourism returns to Amsterdam.
