Finally have had an opportunity to write a review after coming home from our trip.
Check in was easy and quick. We arrived late, around 10:00 pm because of a delayed flight, but Tiziana was available to let us in and show us around. And it is a great space.
The photos and descriptions are pretty much on point - but it is so much more amazing in person. The bedrooms (with their own private bathrooms) were a nice change from a standard hotel room, and the open air kitchen and deck just added to the greatness. Nothing better than relaxing after a day of sightseeing on a nice terrace.
Manzoni Metro stop was only a block and a half way, and there was a grocery store the same distance in the opposite direction, so it was easy to get to places and to pick up water/snacks.
Overall it exceeded any expectations, and would definitely use again if/when we return to Rome.
