Great location -- very close to amazing historical sites while still feeling like a neighborhood of locals. Many cool bars and nice restaurants (and good gelato) within a few blocks. The apartment is fairly quiet with the windows closed despite being on a busy street (the bedroom was especially quiet since it was at the back of the apartment). Communication/check-in were very good and the host was very friendly.
The wifi did not work well but our hosts graciously refunded us a bit for the inconvenience (although we would have been much happier to just have had good wifi). The shower would routinely run out of hot/warm water (even when taking very quick showers) and also had pretty weak water pressure.
