The apartment itself was fantastic. Great amount of space, plenty of seating and working space options, and a solid Internet connection that allowed me to work remotely. Location itself is perfect as it's on a pretty quiet street while still close to everything you need to walk to, including all of the main Roman tourist sites.
Only issue I encountered was with the upstairs neighbors, who were pretty loud at various times, most often in the middle of the night. I'm hoping they're just temporarily there as no one else had mentioned this issue previously, and when I did have problems Massimiliano was very quick to respond and help communicate the problem to the owner of the upstairs apartment. Otherwise, this was a fantastic apartment.
