In case of emergency
You’ve probably been there. You go up the stairs to the second floor of your house, expecting it to end, and then you discover you have to go somewhere else. But don’t you really have to go? It’s not that they don’t. The person who owns this property understands that feeling all too well because they put a toilet and sink on the landing between the two floors.
That is… useful if you live alone, we believe. However, if you don’t, or if you ever want to invite guests over, it’s probably not the best option. Also, we can’t help but wonder whether the real estate agent intended to include that little setup as a second bathroom.
