It was the worst experience since I am using AirBnB. The owner of the property does not share any check-in procedure. You must call them all the time. I did not have local mobile number/ internet as I arrived in Rome from Germany on the same day.
The address is difficult to find even by maps. I reached by Taxi and then had to search for the entrance door of the building which is quite complex when you arrive first time.

The owner will only provide you the check In details ( entrance main gate pin) after you pay 25 Eur for cleaning. For me this extra 25Eur for cleaning was totally wrong as it should be mentioned in the full cost while reserving the place.
If you dont pay these 25Eur , you will receive a false/ fake damage bill of around 150Eur afterwards.
Please avoid this place and better find some other place. So that you can enjoy your stay in Rome.
