We had a good time at this place, but with some caveats.
The bedroom has great natural lighting, it is spacious, and the nice table allows for enjoyable meals. The neighborhood looks safe, and the reliance on multiple physical keys to access the apartment helps build up a sense of security.
The kitchen, although mostly complete, could use a minor renewal of some utilities (e.g. the dish dryer is a bit rusted), and adding a microwave oven would be very useful.
The bathroom has a nice visual design and is spacious, but it has a flaw: there is a switch that turns off the boiler next to the light switch, and it is easy to touch it. The boiler takes around 4 hours to heat up, but we were told it would take only 1 hour. Additionally, after a person had a hot shower, a second shower will be warm-ish at best, and only for a few minutes before the water is cold.
I would recommend this place if you are visiting Rome in the summer but only go in the winter if you are alone.
