Do yourself a favor and stay anywhere else. Hotel Pantheon was, without question, the worst hotel experience we've ever had. This hotel relies on its historic reputation to lure travelers in, then expects them to accept filthy rooms and poor service as part of the experience.
Our room was absolutely filthy. Among other issues, there were bugs, stained sheets, and stained towels -- all of which I have documented. No paying guest should be expected to sleep in a room like this.
When we brought these issues to the staff, instead of apologizing or making things right, we were met with rudeness and excuses. We were told the hotel is "old" and "historical," as though that somehow justifies poor hygiene and unacceptable room conditions. Historic hotels around the world manage to be both charming and clean. This one failed at the basics.
What bothered us most was the sense that the hotel's reputation and historic label are being used to convince travelers to accept conditions that should never be considered acceptable. We paid for a clean, comfortable hotel room and received neither.
If you're thinking about booking here, DO NOT! There are countless hotels that actually value their guests and provide clean accommodations. We would never stay here again and cannot recommend it under any circumstances. Left after 1 day into a 4 day stay due to the absolutely awful conditions.
