Great apartment, clean, lovely, and the hosts were wonderful and responsive. The only struggle we might mention was the location. The neighborhood of the apartment is wonderful, with great food options, on-street parking. But it is a bit from the city center. A little like staying in Brooklyn in a way. It took us more than an hour on public transit to get to the Vatican. The tram is only 15 minutes to the center. While the walk from the apartment to the Tram is not bad, 10-12 minutes straight downhill, the walk back up was tough. Not bad for me, but my wife has some health issues and it was a steep and slow climb, followed by a 4-flight walkup. The other option was a bus... 23 stops to the center, so a long, slow ride. None of this is a deal-breaker, but if we'd known we might have spent a little extra to stay closer in. Also there is a commuter train option, which we discovered using Google Maps.
