The apartment is in the perfect location, very short walking to the metro station and to a few shops. Within walking distance you have the nightlife of the Pigneto neighbourhood and the city centre, so it was well located for us and we did not need to take a lot of taxis (with 5 of us it would have been quite pricey, otherwise).
The flat: it looks just like the pictures. the beds and pillows are comfy and the rooms are warm. Only thing to keep in mind if you are a light sleeper is to bring an eye mask as the curtains are quite thin. It doesn't get super bright, though, so for us it was not a deal breaker.
The hosts: I had a few back-and-forths with them regarding check-in time and myself forgetting to leave the spare set of keys in the house. They were courteous, flexible, polite and very helpful the whole time.
Long story short, I highly recommend staying here :)
