When I lived in an apartment...
I put the washer where the refrigerator went. This refrigerator had manual ice trays, so I could put it anywhere there was an outlet. This way I could run the hoses (or add extensions) if needed to run the fill and drain hoses from the washer to the sink. You can use an y adapter to combine the hot and cold fill hoses, if needed. You can then hook it to a faucet adapter like what is used for a portable washer. Some of the new apartments/houses have those faucets with the pull-down sprayer. Not all of them are compatible with these faucet adapters. This *might* work in the bathroom. In some houses, the bathrooms are quite large. However, there would be a lot of humidity in there from showers. Probably not the best location for stuff with electronics.
I hope you enjoy your new set!
