Thanks to Mariangela and Enzo we absolutely loved our stay in Rome!
When we arrived at the residence Enzo was already waiting and immediately spotted us when we were looking for the exact location of the apartment.
He showed us around inside afterwards and gave us some advice on what to do and how to get around etc.
Communication with our hosts worked brilliantly and eventually we were even allowed to occupy the apartment until the evening of our very last day in Rome, which was very kind because our flight back home left late in the day...
