The apartment is very spacious and it was neat and clean. It is equipped with a washer (but not dryer, you have to use drying rack), stove, microwave and refrigerator. It has three separate bedrooms and three bathrooms (two have the bathrooms attached and one is next door in the hallway and includes jetted tub), decent sized dining room and small kitchen. It is located on 5th floor. You can reach it via very small and old elevator or you can claim stairs. I stayed in Rome several times and it is a typical apartment you will find all over Rome.
They provided towels, sheets and pillows and some extra blankets.
The apartment was very quiet because it was upgraded with dual pane plastic windows which keep the city noise out. The neighborhood felt safe and friendly.
We stayed there in November and the days were decent (~20 C) but the nights got cold (6-10 C) and it is connected to Central heating which is controlled by the city of Rome so we were getting a bit cold at night, because the city decided not to turn it on. This is not a fault of the owners but something to be aware of. It is also equipped with window A/C units so it looks like in a summer you can be in control of your temp.
There are small shops, grocery stores, restaurants all within very short walking distance.
Francesco, who was our contact during the stay was very friendly and accommodating.
I would definitely recommend this apartment and I would stay again but if you are coming during cold months, please check before hand if the heat is on.
