I stayed there with my teenagers (girl 19, boy 13) for 4 nights in August and it was great. It’s a very safe area and I would recommend it as a good value stay for families.
The area is quiet and safe, it’s where all the embassies and government buildings are so not noisy or rowdy at all.
Silvia’s mum was looking after the place when we stayed and she was very helpful and very sweet. The kids could help themselves to snacks, juice, yoghurt etc any time of day and the same for coffee and biscuits.
Our room had a little en suite shower room which was great, but we could use the communal bathroom as well if we wanted to.
There were a few other travellers staying at the apartment while we were there, it was interesting to talk to them and say hello. Everyone was very nice and respectful.
We could have used the kitchen facilities if we wanted to but we mostly ate out.
There is a really good and cheap pizza place over the toad called Pinsere- 5.5 euros for delicious takeaway pizza!
Rome is huge and the apartment is around a 15-20minute walk to the centre so I would highly recommend getting a Rome 24/48/72hr travel card which covers unlimited travel on buses, trams and the metro. It only costs 7euros for a 24 hour pass and you can hop on and off buses etc as much as you like. There are lots of buses that stop nearby.
Overall I would highly recommend this place.
