This is a lovely apartment in a brilliant location. Trastevere is a beautiful area and a fantastic location for food and drink of an evening. The apartment is within walking distance from all the major sites but there are tram stops close by if you prefer to use public transport to get around. We got the train to the Trastevere Station and then the 8 tram to Belli from the airport. This was much cheaper than a taxi and very simple to do.
Marco is a great host with fast communication. Check in was simple and the apartment has everything you could want for a short break. Highly recommended!
