The location was good and quiet, short walking distance to the Colosseum around 10 minutes, there is also an underground train station by the Colosseum, there are few restaurants around the area to pick from. Also you can walk to the trevi fountain which is around 25-30 minutes.
The apartment is well laid out and clean, the shower worked really well, the wifi is ok.
Only thing I would say is better improvement to the locking system, it can be a chore getting inside the apartment from the outside, especially the middle gate (if it's locked at times you have to try several times to unlock it). You have to got go through 4 barriers and if you don't have an internet connection to do virtual unlock then you have to type long password keys for two different sets of doors and make sure you turn it a certain way.
Overall I would say it's a good location.
