A picture is worth a thousand words. Besides the attached photos stating "Disgusting hotel with health risks from mold and mildew caused by substantial lack of air circulation in the bathrooms and high temperatures with no air conditioning, this hotel has several other troubling issues, which are noted as follows:
* On the last night of my stay, detrimental and incredibly loud music was being played by the hotel hostess on duty, in which she turned it up even louder when I requested to have it turned down. It lasted until 2:30 am. She apparently has mental problems. But when I wrote to the management (who also appears to have issues with reasonable guess and is unwilling to provide their names) after departing and requesting a full refund due to the insanely loud music resulting not only in my sleep deprivation, but for completely disturbing my vacation, the manager had a flippant attitude and said it was "normal" for such troubling loud music to be played until the early hours in the morning. And he said he was not worried since the local Rome police typically turn a blind eye to such disturbances.
* Even though the hotel claims to have a no smoking policy, smoking was definitely occurring my stay at Relais Orso Hotel, in which it smelled like marijuana (an illegal drug substance in my country).
* Old metal keys (very unsafe) are used along with electronic card keys for the rooms, in which getting a "Do Not Disturb" sign does not exist in this entire hotel.
