So the hotel I'm staying at looks like any old corporate building from the outside and has the kind of ambiance of a youth hostel, but I was really surprised at the character as well as the technology on the inside.
When you put the key into the door, you're welcome to a small room... with another door. This is where you're supposed to take off and leave your shoes before you come into the main living area. I did take off my shoes, but the idea of wearing the slippers bothered me a little bit, so barefoot I go! Also the heating is under the floors so it actually feels good to walk around with bare feet.
