Overall, I would not recommend the Pantheon Iconic for multiple reasons, including poor recognition of elite benefits and poor engineering standards. I spent most of my stay wishing I was spending a second night at the Westin or had tried the W, which was close to the same price. Frankly, I even thought the location wasn't as good as the area was full of tourists and clogged sidewalks, and the restaurants I preferred were much closer to the area of the Westin, W, STR, and Regency. Here are my pros, cons, and photos:

Pros:

• The bed wasn't bad - I slept for 12 hours as I didn't really enjoy my awake hours at this property - the mattress was just-right/firm, the pillows were a bit hard, and the covers were okay in thickness - I did enjoy the feel of the linens, and obviously, I slept well
• The breakfast was pretty good - a full-ish buffet - I was offered an omelet but was worried they would charge me, so I didn't accept - the salmon, scrambled eggs, and croissants were pretty good, though - surprisingly, I wasn't charged for the cappuccinos (I was convinced I would be)
• There was a bottle of champagne and some Italian pastries in the room - the pastries were kind of oddly crunchy

Cons:

• Rude agent when I walked by the hotel at 10 AM and asked if perhaps my room was ready - "check-in is at 3, just check the Bonvoy app"
• My bathroom smelled off and as if something had been masked with a lot of cleaning fluids. I then stepped into the shower and started hearing gurgling noises, realizing that every time I pressed my foot down on the shower floor, I was spreading a thin layer of water that was gurgling underneath the stone floor. The smell seemed to be decay from that stuck water underneath the floor. I called down - they sent Housekeeping up who just sprayed more noxious cleaner / perfume. I went down to the front desk who told me there were no other rooms and that if I wanted to leave that I would have to pay for the night anyway. Then, they sent an engineer up who said that everything was fine and acted like the gurgling water was normal. Whatever, I was stuck there anyway as I wasn't going to waste 500 EUR, so I just went to sleep and left early the next morning after breakfast. The fact that a hotel would keep a room like that in service when water damage would be accumulating and potentially causing large problems in the future show their priorities of a quick buck over anything else.
• The hotel refused late checkout as they were "sold out", which they said was a good thing for them. They told me I could have 1 PM, and honestly, it didn't matter as I just wanted out of this gross hotel as early as possible.
• Only upgraded to a Deluxe Room even though Junior Suites were being sold online at the time of check-in
• Shower pressure was bad, and the half-glass means that water leaks out onto the floor
• The light switch design is idiotic with no indication on most of the panels of what is being controlled (just three random dots)
• The deadbolt on the door did not seem to work (it would just rotate)
• Zero noise isolation in the room (you can hear everything around you, above you, and below you) - someone was at the front desk complaining about spending 900 EUR just to hear their neighbors
• No Internet TV OS - advertised Chromecast functionality leads to a "Not Available" page and most of the channels that I tried also said "Not Available" - the only channel I could get to work was CNN
• Shower pressure in the sink was too strong (ironic as the shower was bad), which meant that water sprayed out all around
• Some gross cleanliness misses - sticky substance behind the chair pillow, some large debris left in one of the drawers
• Very few accessible outlets - only one in the bedroom that I could find - everything else (bedside) was a USB Type A plug, which is useless as most chargers these days are USB-C
• Some of the hallways smelled bad and had trash left on the ground (used masks) my whole stay
• Ridiculous need to write your credit card number down on a paper form at check-in - seriously, it's 2022 (though, I found the same at the St. Regis where I'm at now) - I don't think the Westin did this, so I don't think it's a Rome thing - sure, type it into your computer, but a paper form? Come on...

Overall, I would strongly recommend not staying at this property. I will not be returning.
