While other rooms in the hotel Artorius might be ok, we have got Studio room in Annex Building. The entrance was behind the corner on Via dei Serpenti. The door led to a long corridor with another lock door and tiny courtyard with almost no sunlight since it was more like a well inside the building. The room window opened into this patio, not outside the building. After entering the room, I immediately mentioned humidity, musty smell, and luck of ventilation. No iron, no safety box. In my opinion this part of the building has never been a living space, but rather a ground floor storage, converted to “hotel rooms” by owners to maximize the profit. They apparently have no shame in setting up such a tourist trap. Ok, here comes my one star review as a payback.
