Within walking distance of many of Rome's main attractions and mere steps away from the Trevi Fountain. You wouldn't realise though since the apartment is located towards the back of the complex so you do not hear or see any of the high pedestrian activity! There is a steep, narrow staircase to navigate in the building so be mindful if you have accessibility issues.
It may be a good idea to bring earplugs in case your neighbours return late as noises in the corridor can be heard very clearly from the room. You also look out into the atrium of a restaurant that may play loud music sometimes, but I thought this was faint compared to the corridor.
The room itself has everything you could need for a short stay in Rome and the amenities are quite updated, particularly in the bathroom. There is plenty of space to lay out your luggage and lots of cupboard space if you want to hang some clothes instead. They are kind enough to provide some washing detergent for you to use the washing machine too!
Dunia was great with communication throughout the process. She was also accommodating in letting us check-in slightly earlier than listed, and her assistant, Andrea, was a pleasure to meet.
