This apartment is clean, stylish, and in one of the absolute best neighborhoods of Rome, full of bars, restaurants and interesting people. It's very lively (don't come here if you want solitude and quietude), with piazzas around every corner, street musicians- it all started to come alive at noon and stays that way until well after midnight. You're in the center of the action, and near the Vatican, Colosseum, and many other major sites. Easy access to the airport. The host was sometimes responsive and sometimes not, like when I needed to know about parking or how to get a 2nd sheet for the bed (which never materialized), however the amazing apartment and neighborhood more than made up for it. The person who let me in said I needed to pay a 3.50Euro daily tourist tax per person, however as this was never discussed or agreed upon beforehand, I didn't oblige. You may want to check that out (I was also asked to pay a tourist tax in Venice, so it may very well be legit, but I wasn't sure at the time and don't appreciate hidden fees!)
Still overall, high marks for this apartment which is sure to please.
