The apartment is quite big, it has 3 rooms with queen size bed in each of them and couple of additional single beds, so we were able to host our entire family of 9 people easily. Besides we were provided with a baby cot and high chair which was quite helpful. Each room has an air conditioner which saved us from melting at those hot days of 40 degrees Celsius.
There are 2 bathrooms in apartment, so there won't be any queue to bath at mornings. The kitchen is quite big and filled with all the necessary stuff.
Apartment was exceptionally clean! Check in/out went flawlessly. We also liked the welcome chocolate cake that waited us right after check in :)
The only issue that we've encountered is that the streets at the neighborhood are quite dirty and filled with garbage, perhaps that's because the streets itself is located near the Termini railway station and there are a lot of homeless people walking around. Also it was quite noisy on street at nights so we had to close windows in order to reduce the noise and get some sleep.
