It's difficult to rate Serena apartment.
The view is really nice, the apartment is fairly spacious.
But at the same time we had a few issues like dead light bulbs (they have now been replaced), clogged shower (now fixed), the washing machine unusable, an iron without iron table (now fixed, Serena bought one, which is really nice).
The Wi-Fi during the weekends is barely usable, I could not do any video call (speed around 680kb/s). It's better during the week and during the day (around 8-10MB/s). It is not Serena's fault though, internet in Italy is awful overall as the same connection will be shared by multiple buildings, but important to remember if you care about that. Wi-Fi often barely working from the bedroom (a repeater or better router would be a nice addition).
The location feels a bit far from center attractions sometimes, but at the same time it's good because it's a calm place. Do note that the public transports (especially bus and trams, subway is fine) are not particularly good in Rome (very often late or on strike), so sometimes that can be tiring.
