"DO NOT STAY HERE!!!! Stay literally anywhere else.
Sadly this was one of the worst hotels I've ever stayed at and I wouldn't recommend it under any circumstances. I booked based on the solid reviews and because I always have positive experiences at Hyatt properties - this one is the exception.
The service is horrendous here and it's mainly due to incompetence. The rooms and rest of the property are terrible too. We were here for 4 nights and were in town for a family wedding - many of the staff's missteps really affected our experience in Rome and almost made me miss a wedding event.
I was traveling with my 65 yr old mom and the first room they put us in didn't have a door to the bathroom - the view from the bed literally looked directly at the tub shower. Now for the tub shower itself - the most ridiculous setup I've ever seen in my life. First of all, the tub was EXTREMELY slippery. I almost fell 2 times while showering and did not allow my mom to take a shower in there. Second, there was a giant window in the shower with a heavy curtain. So as you're showering, you're literally soaking this curtain. Also the sink wouldn't drain normally so any time you used it, the entire thing would fill with water completely and then take 5 minutes to slowly drain.
When I went downstairs to request a room change, the man at the front desk scoffed and said "that's a really nice room..." okay...? Nice for WHO exactly? I told the front desk we needed a new room because we need to get ready for a wedding event and he asked how long it would take for us to gather our things, I said about 10-15 minutes, so he said ok pack your things and I'll move your room. I thought ok great ... fast forward TWO HOURS LATER, multiple visits downstairs, until we finally got our new room. We literally packed our things and sat in the room for 2 hours and when I kept pressing him he made it sound like he was doing us a favor even bothering with the move. Also, he tried to say that he got us a "complimentary bottle of wine" as a courtesy ... LOL, our previous room had one as well when we checked in .. so he straight up lied to my face.
Anyway, once we changed rooms it didn't get much better. The rooms are laughably small and so are the bathrooms. Terrible lighting, no ventilation, and things just don't work. Halfway through our stay the phone stopped working. I had to use the one in the hallway. We had one other pair of friends stay here and their shower stopped working halfway through the stay. We had friends that stayed at hotels super close by that paid 30% less and got so much more. Don't fall for this being a Hyatt property, you're going to be super disappointed.
A few other things to mention - their terrible iron ruined my brand new white dress shirt (left weird black marks all over it) so I had to wear a backup to the wedding. The other front desk staff was equally as incompetent - when we were leaving for the train station I asked if we should get 2 cars or one large one (my friends were also staying here). First he said he can get a van ... then he said there's no van so he'll call 2 cars .. then he said he got a big car ... car comes and it's a tiny taxi. We basically wasted 20 minutes sitting in the lobby when we were running late because of that."
