Excellent communication; I arrived in Rome at almost midnight and called for help with check-in and a shuttle and received immediate responses, and were very helpful. The location is great- walking distance to a lot of Rome's great tourist sites, restaurants, and shopping.
However, bathroom and kitchen were not always clean; probably from other guests and not the fault of the owners (since those two are shared spaces with other guests)
But out of my 3-day stay, wifi didn't work from day 2 which was very inconvenient but the worst was that on the last night there was no power AT ALL so no electricity in the entire apartment to charge my phones, no lights on when getting ready, ICE COLD shower, no ability to make a coffee before heading out. This part I didn't understand/enjoy.
