We (2 adults) stayed in the michaelangelo room and it was almost perfect. Spacious room, excellent location (short walk from all the good spots), friendly checkin, loads of towels and reasonably priced.
The only issue we had was every night at between 11:30pm -6:30 am (like clockwork) the sound of a television heavily vibrates through the roof and walls - it was so loud / clear that you could hear the words. I raised it with the hosts who said the room above had moved out after the first night, however it continued for 3 nights in a row. There is no other street noise as said in the description- just the sound of the tv. After searching though other reviews, this appears to be a reoccurring theme. I think it is only relevant for the Michaelangelo room.
If you can deal with the sound of the tv,
And can fall asleep easily, then this is a great place to stay.
