Angelo was very nice, he helped a lot and even picked me up at the airport. He showed the apartment and from time to time asked if everything is fine.
The room was clean, the rest of apartment was relatively clean (the guy who lives there did not clean after himself so there was a mess on the kitchen and bathroom sometimes).
The thing with the water pressure was a bit problematic: we had to open all the faucets and wait a while till there will be a hot water.
Wifi worked very good, we didn't have problems with that.
And location of the apartment is good, 5 minutes walk from Tiburtino, easy to get to metro and airport, etc.
