My wife and I stayed in this apartment for over a month, and could not have been happier with it. The location, safety, comfort, and ease of access to anything we wanted to see or do was absolutely amazing.
Combine that with the helpfulness of our hostess and how easy it was to reach her and communicate with her throughout our time here, and it was such an incredible introduction to Rome that I don't think we could have asked for much more.
The apartment is located between the Vatican and the area known as Trastevere (where some of the best food is available), and both are within an easy 10 minute walk.
Just across the Tiber, no more than 15 minutes' walk, you enter "downtown" Rome where most of the history begins. My wife and I easily walked to the Colosseum, Pantheon, and almost all other major Roman attractions without even using the bus. It's like this place is located right in between all of the places you would ever want to see in Rome.
Speaking of the bus, there is a bus stop DIRECTLY outside the apartment building, meaning you will not have to walk in the rain if you need to catch a bus during bad weather (which though we had almost none of the entire 5 weeks we were in Rome, the bus stop made more enjoyable when we did encounter it). If you decide you would rather use the bus than walk, you couldn't stay in a better place.
The apartment itself is located on the ground floor in an inner courtyard to an apartment building, meaning after we came into the front door of the building, we had a private (locked) entrance to our courtyard before we even got to our apartment's door. This made me feel very safe allowing my wife to stay inside the apartment by herself when I went out.
The apartment looks just like it does in the pictures. It is very well represented, and was quite comfortable.
Also, our hostess was AMAZING. She explained things clearly and politely, and if we ever had a question she responded to us in a timely manner in a way which did not cause any issues with the language barrier. We could not have been happier with her, and we were so, so thankful for her.
Finally, as my wife and I have traveled a LOT, a quick note to Americans:
This is ROME, and if you are an American, please remember you are visiting another culture and are not going to be staying in an American apartment, but a truly ROMAN apartment which is smack-dab in the middle of Rome.
This means you will be able to experience all the charm and amazingness of Rome, and you will be living like a Roman. You will, for instance, have things like a washing machine, but you will need to use a clothes rack to dry your clothes. You will not have a dishwasher, but you will have a microwave and stovetop... see where I am going with this? You will be living like a Roman actually lives, which is beautiful and romantic.
Also, Rome is a noisy city and the buildings are history themselves, and as in any major city you will sometimes hear your neighbors, the city sounds, and the rain. I loved it.
Finally, they recycle virtually everything, so make sure you are clear about how the trash works when you check-in because I got confused and it made for a fun (and funny) meeting with our truly delightful neighbors =)
Overall, I would vote this a HUGE and AMAZING place to stay (I'd give it 11 stars if I could), and I hope you treat Sabrina well if you choose to stay here... this place truly helped create a life-long memory for us in Rome, and I can hardly imagine having a more accommodating, safer, and better located place if I had tried.
Thank you Sabrina, and I hope you have tenants which deserve your place, because it is wonderful.
