If you're down to be in the heart of everything Roma, go to Trastevere and stay here. The rooftop was insanely beautiful, the outdoor shower a huge plus. Our first night (in the middle of June) was very hot and a bit buggy (no A/C, as is typical in Rome), and loud partying from the street below- but after we found the fan, and turned on the white noise, we slept like babies. Worth every bit of the figuring out to get our own beautiful apartment with a rooftop!
