Marika's apartment was just perfect! Well located quite close to bus/tram 8 running straight to downtown Piazza Venezia. The same line is also a few stops from Trastevere train station, with Regional train connection to Fiumicino airport (Bus tickets are 1,50 euros and Regional train to the airport is 8 euros).
Communication with Marika was easy and she is a very kind and attending host. Everything worked out just as promised and agreed. I am happy to recommend her place and will gladly come again, when back in Rome the next time.
