The best thing about Carmine's apartment is the great location in Trastevere. I would recommend the area to anyone who is interested in avoiding the hustle and bustle of central Rome and immersing into the local lifestyle and nightlife. Definitely try the lovely bakery across the street, Le Levian, which became our regular breakfast spot. The market on the nearby piazza is a great place to stock up on delicious and cheap fruit for snacking during the day.
The flat itself is quite basic and I don't imagine it is suitable if you are after a romantic stay. My sister and I were after a budget option in a good location and had a good idea of what to expect. However, we hoped that the host will make up for the basic conditions with great attention to detail which we were disappointed to see was lacking. The bathroom and shower could have been cleaner, there was no phone coverage in the flat and we had to restart the Wifi router after it stopped working to get a decent signal. This made it difficult to plan our activities for the day. Also, the dampness in the flat is definitely an issue and the efforts that have been made with the air conditioning and dehumidifiers only help to an extent. There were no amenities such as shower gel and shampoo which I tend to take for granted in my experience with airbnb in UK and other European countries.
Overall, great location but only suitable for a short stay on a tight budget.
