My mother, sister, grandmother and I stayed 3 nights in the nice apartment. Paolo was super friendly and helped us a lot. However, there was a issue with the lock/the door which meant we one night could not enter the apartment. Paolo helped us but it took more than an hour. Hopefully this will be fixed so it will not happen again. :-) Moreover, apparently two chairs were broken so there were only 3 chairs at the dining table in the kitchen which was a bit annoying when we were 4 persons.
We had a late flight which meant we needed to store our luggage. Paolo recommended a place 800 meters from the apartment. A bit inconvenient and it would be nice if it was possible to store it nearby. Overall, it is a very nice apartment. Also if you are 4-5 persons. I will definitely come back next time I am in Rome.
