What a wonderful place. Super centrally located, walkable to just about anywhere in the downtown Rome area. And if you enjoy a bit of a walk (~45 min to 1 hour depending on pace) not too far from Vatican City and some other great (lesser known) landmarks. We didn’t need a taxi until the end of our trip and even then only because of our luggage, even termini train station is walkable if you desire.
A few notes for guests, there is a set of narrow stairs that might be difficult for some to carry up large suitcases etc. Also as others have noted the keys can be a bit tricky on the front door, though this is likely an issue with the building rather than just the host (saw some of the residents having the same trouble). We didn’t find either of these to be much of an issue
There is great food if you stay away from the more tourist filled areas, and even wandering around somewhat aimlessly through the various alleyways was incredible. Lots to see, experience, and eat. Lots of amazing ruins, churches, art, etc not mentioned in guidebooks.
Overall was a fantastic stay and would recommend to anyone
