Fantastic gem of a Airbnb. The hosts are incredibly helpful and friendly, and provide a nice curated list of recommendations.
On top of the spectacular view of the Trevi fountain from the room, the hosts have done a great job recreating a hotel like feeling. Highly decorative, complimentary snacks and drinks, washer/drier, countertop espresso machine, etc. etc. I generally enjoy Airbnbs where you feel in tune with the city, but this place is a welcome exception - they nailed it.
It's also true to the pictures, it's every bit over the top as it looks. If you appreciate that kind of thing you will love the room. If that's not your preference, it's easy to overlook and enjoy the fountain view. Either way, highly recommend.
