Amazing location, one of the best craft beer bars in Rome is next door, and a bunch of non-touristy truly Roman restaurants with 500m. Weekend nights are noisy until 2AM, so bring earplugs, headphones, or a portable speaker.
Arnel was super flexible with the check-in, and the place was spotless. There's even a great balcony with a table for sunset meals overlooking Trastavere!
