First, the positives: The apartment is centrally located and close to everything. The pantheon is a 5-7 min walk away. The air conditioning is ice cold, which is hard to find in Rome. The apartment is very big, plenty of space for four adults. One bathroom. Marco was very kind to us, and helped us with our luggage. We only met Marco. The apartment is about 40 steps up from the street. Street noise is minimal. There is no lift.
Negatives: The apartment is pretty weathered. It is obvious many things need to be updated. Pillows on the couch are dirty and a color that is supposed to be white. The couch and ottoman are dirty. Linens looked grimey, the bed and mattress are beat. Extra blankets looked old and decrepit. The shower had spots of mildew, the doors looked dirty. I am 6’0” and barely fit in the shower. There are no toiletries. Bring your own soap, shampoo, etc. we had to clean out the clothing drawers from small hairs. Do not plan on cooking in the kitchen. I found half a can of espresso for coffee. There is a moka pot, no American coffee pot. There is a washing machine, but no detergent.
The upstairs neighbors were very loud until well after 1am. Dragging chairs around, crying babies, yelling. If you plan to go to bed before 12, good luck. We used a noise machine and ear plugs and still found it tough to sleep.
I would not stay in this apartment again, there are too many options in Rome to accept the negatives.
