The location is great. Very centralized with easy access to all the sights. The apartment is clean and very spacious. Internet is fast (400Mbps for us). And the host is warm and welcoming. We recommend this place and will try to stay here again when we return to Rome.
Do be prepared to stay his a historic building (no elevator; small spaces/passages). While the shower is small by American standards, I’m 6’4” 260 and I had no problems without banging elbows - so you can too. The living area faces the Pantheon, which means you’ll get some street noise - that includes cellists, opera singers, carolers, etc. for free ambiance (but the bedroom is at the back and nicely quiet). All of this is part of the charm of sleeping in a 500 year old building with a view of a nearly 2,000 year old building next door. Loved it!
