Antonella's place is located in possibly one of the best areas in Rome. The street is quaint, and as soon as you walk around the corner, you run into many great restaurants and tourist attractions to visit. My mom and I felt comfortable and right at home. The place was clean and has a lot of natural light coming in, the decorations were nice and unique and not to mention that Antonella is one of the best hosts we've had - thorough yet brief overview of the place: from tips on restaurants nearby, to the wifi code and even a nice welcome baggie with a small bottle of wine. She also helped me to reach a shuttle service to the airport after many unsuccessful attempts on my part!
The one tough thing about Antonella's place that others have mentioned are the stairs - get ready for a nice workout upon check in and check out. Definitely worth it though! We loved our short yet memorable stay!
