Valentina's apartment is amazing. As others have mentioned, it's even larger than it looks in photos and is very light, clean, and airy. The memory foam mattress was perfect. The terrace is incredible. The apartment has everything one could possibly need, and Valentina very thoughtfully provided coffee, milk, prosecco, bread, etc.
Valentina also went above and beyond, meeting us at the apartment at 2 a.m., after our flight was 15 hours late. She also arranged transportation to and from the airport and provided us with some great recommendations for restaurants.
Even though the neighborhood is extremely lively, it really was not loud at all at night. The cobblestones on the street were being replaced during our stay, which made the mornings fairly loud. However, the construction was nearly over by the time we left, so that will not affect anyone else's stay.
The location is perfect; we didn't once take the (readily available) public transportation or a cab.
I would definitely recommend the apartment to anyone, and it would be especially perfect for families.
