Hi, we just got back 2 days ago from staying in a Kid's Suite at the Portofino. I had similar concerns after reading the reviews, but we found the hotel to be clean and the staff was friendly. The a/c unit was noisy, but not to the point that it bothered us. The WIFI was not great...although we did find one location in the room where we could consistently have a stable connection. We requested a room on the top floor, as I had read that the noise between floors could be irritating. We didn't have any problems with hall noise or noise from neighbouring rooms. All in all, if the price was right (which it was for us this time), I would not have any concerns in staying at the Portofino again. Have a great trip!
