We had a great weekend stay at Aurora's lovely terrace apartment, which was even more charming than the pictures showed. The apartment is excellently located, a short 15 minute walk from the Vatican (with numerous restaurants along the way) and the Metro is just 10 minutes walk (navigating to primary sightseeing spots is easy from there). Davide, Aurora's friend, was super helpful checking us in and out, and both Aurora and Davide were easy to communicate with by phone/text when we had questions. Numerous decorative touches added to the charm and homey feel of the apartment (so much better than a hotel room), and the terrace (lined with a pleasant array of potted plants) is the perfect spot for enjoying a late-night bottle (or two) of fine Italian wine. We felt perfectly safe in the neighborhood, which has a lively residential city feel but quiets down after midnight even on a Saturday night. There are two fantastic restaurants within a block (one right beside the apartment called Vino Bono, and Tulait Srl just around the corner). We most definitely hope to return to enjoy this lovely spot once more. Grazie mille!
Tip #1: after checkout there is no luggage storage area at most personal apartments like hotels have -- BUT the Termini station on the Metro has luggage storage for a small fee (look for the Left Luggage signs).
Tip #2: If you need a taxi, download the MyTaxi app onto your phone and you can order a taxi straight to your actual GPS coordinates (and see the taxi coming on your screen). I believe this works in much of Europe.
