The main thing is a gorgeous location! In the heart of Rome.
Also it is very good to sleep - it’s quiet place, comfortable mattress, blackout curtains.
What’s important for the winter — it ‘s warm place.
We was a little disappointed about cleanliness - some staff wasn’t sparkling clean, some furniture needs cleaning.
Also you should consider all windows have a view to the other buildings. It’s not a big deal.
In total — it’s a very good variant in Rome!
