This apartment is more like a castle. It's two-thirds of the top floor (5th storey to Europeans, 6th storey to North Americans) of an building right near downtown Rome, plus THE ENTIRE DAMN ROOF. It's also stunningly renovated - it looks recent, and it's beautiful. I'd guess it has 13 or 14 foot ceilings. Everything is really nice and looks quite expensive. The waterfall shower in the master bathroom even puts out North American shower amounts of water, a rare treat when travelling in Europe!
Check in was easy - a few days before the booking, the owner Sveva gave me the contact info of her property manager Laura, we talked by Whatsapp and set a time to meet on our arrival day. Laura was very professional and friendly. We had a minor incident with the door lock (it jammed) and she was at the apartment within 20 minutes to fix it.
The only real negatives was that the roof isn't very well maintained (it's definitely not received the exquisite renovations and maintenance that the apartment itself has). But overall, this is a great place to stay in Rome if you're a large group. It's not cheap but if you split it between 3 or 4 couples, not sure you're going to find anything this nice for anything close to that price, this close to downtown Rome.
