Not OP, just an admirer, but:

1. If you have the cheese for a WaterRower, it’s quiet enough that you can haul ass in your studio apartment for 90 minutes without bothering your neighbors
2. Rowing burns a fabulous amount of calories with the smallest possible footprint - you take up a rectangle of space for the entirety of your workout and at the end you’re still exhausted
3. Full-body workout baby
4. Naturally builds a functional-looking body, not too grotesque, very 3D
5. As long as you keep it clean, no one will notice you’re not using your rowing machine - it’s pretty obvious when you’re not using the 32 kg kettlebell in the corner
6. There are cool apps out there for rowing machines, but without the prohibitive expense of Peloton
