This apartment is right around the corner from the Pantheon, which has a beautiful Piazza and fountain t hang out at. It is a nice walking distance to other piazzas, the Coliseum, Forum and lots of restaurants and shopping. There were always taxis at the Pantheon, so easy to get to Vatican City and other areas of Rome. The balcony is great - views of the neighboring building, but a quiet and relaxing place to have a glass of wine. Olivia is a great resource and very responsive. They have an air conditioner in the bedroom and in the living room which was nice to cool down on hot days. And lots of hangers in the closet.
The downside is the photos of the apartment do not match the actual place. The bed sits about 12" off the floor, so not easy to get in and out of. The mattress is also not comfortable. The white leather couch in the living room is peeling and gross. There are lots of dings and dents in the walls and exposed wires on a lamp that didn't work. Bathroom was fine and clean and we didn't really use the kitchen, but it has a mini fridge, stove and microwave. The biggest factor to consider is if you plan to bring a suitcase bigger than a carry on. The apartment is up 3 flights (almost 100 steps) and no lift. The last flight has scaffolding as there is work being done, so it would difficult to get a big suitcase through there.
If you don't plan to spend time in your apartment, this is a great location and we had a delicious dinner with great service at the restaurant right next door called Miscelania. They have outside seating and none of the flower and trinket vendors bother you while you eat.
