Book. This. Apartment.
The place was super roomy, super clean, and most of all the view is INSANE. Every single night was spent just sitting on the balcony looking out at the scenery. The neighborhood is absolutely beautiful. I'm from NYC so I'd compare it to Brooklyn Heights. Has the same feel - not a ton of tourists (some near the basilica), but still things to check out if you're new to the city.
Definitely will return.
