I am surprised no one mentioned this in the other ratings. This seems very crucial to me as a frequent Airbnb user: you are not able to use any electronic power in this apartment without all of the lights on. All of the power is operated by a single key, so use of appliances and normal power operations is connected to the lights of the apartment. You cannot charge phones, operate AC or heat, or any other appliances at night while you are sleeping or while you are out exploring Rome.
Also, you are unable to use more than one appliance (microwave, AC/heat, wall chargers, etc) in the apartment without shorting out the power because the unit is unable to withstand normal operating power levels for everyday use. We barely used any power in a day because we were out all day, yet the power quickly shorted in the evening when we had just returned.
On top of this, the host was consistently unresponsive and required more than 3 hours to respond to our needs (which was critical when the power shorted in the evening and we were left without the ability to heat/cool the room, turn on lights, or lock the electronic entry door).
Also the bathroom is incredibly small.
