Aquarium placement

Leaving the aquarium directly on the floor is often a bad idea. You may have problems draining water. An aquarium that weighs less than you may be placed on sturdy furniture that you can test with your own body weight.
For larger aquariums, you should preferably have a stand or furniture that is made for the purpose. It may be an idea to check what the insurance company thinks about the matter.
If direct sunlight reaches the aquarium, much of your free time will be spent removing algae. A seven-year-old child's bedroom is not always ideal either. Avoid the hallway as well; the surroundings should not be too stressful for the fish.
The aquarium should be in a quiet but clearly visible place where it can be watched in peace. If you put it somewhere you have to seek it out, over time it won't get the attention it deserves. If you put it in a place where people and animals race past all day long, it will never settle down and show its best side as a dynamic, alive and fascinating underwater world in miniature.
Fish get stressed if people stress around them, and bettas are solitary creatures that thrive best in quiet surroundings. The living room or bedroom is good. These are usually quiet rooms where you spend some time, so you get the chance to enjoy the view of the fish in peace and quiet. If you place the aquarium in the bedroom, also think about your own peace of mind; pumps make noise. Are you one of those people who must have absolute silence when you go to sleep, or does the hum of the pump help you sleep even better?
The kitchen can be used, but there will be a few more hygiene considerations, and I think especially about what we expose our fish to.
Some have an aquarium in the bathroom. As long as the aquarium is never exposed to cleaning agents or cosmetics, there is no reason not to put it there. Then you can also spill as much as you want when you change the water.
