Andrea's place was great. Location is very convenient: steps from the Metro, 24/7 store nearby, shops and restaurants abound. Andrea was helpful and communicative. The apartment is very clean, cute, spacious, and feels extremely safe with a bank vault-style door (maybe that's standard in Italy, but I loved it. Very mechanical). We didn't think it was particularly noisy, but we're from NYC, so take with a grain of salt. Ear plugs were provided but not necessary. WiFi was very fast (~50Mbps).
Only thing to keep in mind: ceilings in the loft are somewhat low, especially in the upstairs bathroom (the only shower). I was fine, but if you're much taller than 6'2", you might have trouble.
