I stayed at Marco’s Trastevere apartment for 1 month, and it was a good stay. I didn’t have any problems while I was there. The few times I did send a message to Marco, he was quick to respond. I liked the Trastevere neighborhood. There are plenty of restaurants and bars within a 5-10 min walk. There is a big grocery store (Conad) a few minutes walk away, and I was fine walking from the apartment to all the touristy spots. You can map out the distances for yourself, but it’s about a 30-40 min walk depending on which landmark you want to visit.
