It tastes fine at my house, but at other people's houses, it usually tastes awful to me.
This part is the same for me, I tried drinking it at my friends house and it just isn't the same haha.
A long time ago I bought a huge bottle of bottled water and whenever I finish that I just refill it with tap water, but only at my house. I never drink tap water anywhere else as it just isn't the same.
