I stayed here for 8 nights on my own and loved it. The location is fantastic, I walked everywhere and didn't take any taxis. You're in the middle of all the most fantastic shopping in Rome and minutes away from Villa Borghese gardens, the best place to go for a magical afternoon walk. The downside of the location is that it's extremely touristy, so the cafes are not very good and you have to be careful to avoid the tourist trap restaurants.
The internet is very strong, good for Facetiming and streaming. I felt very safe since there's a restaurant with outdoor seating right by the entrance (although you can't hear it at all from the apartment) and the apartment door has a manual lock on it. The bedroom has blackout shades and a great selection of pillows.
Only criticism I have of the apartment is the water pressure. The shower head didn't work, so it was only a handheld, and the hot water was not consistent (it kept going from hot to cold). The bidet also had very little water pressure. Overall, however, I would highly recommend this apartment and Alessandro, who was a wonderful host and arranged for a black car transport from the airport. Grazie mille!
