I stayed in Diana's apartment for almost 3 months while working in Rome, and it was great! It really felt like home.
First, Diana greeted me warmly when I arrived in Rome. She helped me to get settled and showed me the neighborhood.
Second, the apartment is spacious, comfortable, cozy, and has a fantastic location. The entire apartment has huge windows which let in lots of light, making the apartment very cheerful. The bedroom is a perfect size for 1-2 people, with an armoire, a large closet, and a huge, comfortable bed. The living room has a sofa bed, table for four people, TV, and kitchenette. I found the place to be the perfect size with the right amenities for my stay, and very accommodating for my out-of-town visitors. The WiFi is dependable and the air conditioning works well, too. My favorite part of the apartment was the roof access. The scene from the roof felt quintessentially Italian; you can even see the Pantheon if you look over far enough. Set up with a table and chairs, I enjoyed many a meal on the roof. Laundry is also located on the roof, which is great. The building itself is very quiet, with only four apartments. The street outside is busy during the day, but quiets down significantly at night. The location is also one of the best parts of the apartment. It is located right in the heart of the historic center, a 30 second walk from the Pantheon. Whenever I was out exploring and needed to use the bathroom or have a glass of water, I was always able to quickly get back to the apartment. I can't imagine a better location for exploring Rome.
Finally, Diana and her family were extremely welcoming and reliable. Diana always responded to my emails quickly when I had problems (such as not being able to work the TV and losing my keys). I made a terrific choice choosing to stay in this apartment, and I would highly recommend it as a base for your Roman holiday.
Grazie mille, Diana!
