Emi, Pie's brother is a very patient host and very helpful.
The area is a bit dodgy with lots of different cultures. Emi said it's one of the last authentic parts of Rome. You can get there with tram 5 and 14. A direct tram from Termini trainstation to the airbnb, that's convenient.
The flat is very colorful and full of musical details. This place is not for ppl who look for luxury or everything 100% working like in a hotel. If lucky you can have great ppl staying there. We had lovely Canadians staying. If bad luck with the ppl staying there than the flat might feel to small.
