Stackable front load washer/dryer opinions

[RedDeer17]

Our laundry room is on the second floor. On top of that dryer hookup is on the left side though all laundry pairs doors setup that way that it should be other way around. Only dryers have reversible doors. Now we're thinking about stackable option. From one point of view it should decrease vibration which is critical for the second floor laundry and would save space. Dryers control panel would be pretty high, but we found one laundry pair where dryer has option to move control panel to the bottom if you want to use the pair as stackable.

Do you think it's a good idea to use stackable laundry on the second floor?

P.S. Sorry, should be posted in Home & Garden forum instead...
