This was a really great experience - Michele is one of the nicest hosts I've ever met. He was consistently in touch whenever I needed anything, helped me stay at another flat when I had booked the wrong dates, and even had some wine and beer in the fridge ready for my arrival.
The apartment is newly renovated and very clean, it's also on a very quiet street - which is rare for Trastevere. There was sometimes a tiny bit of TV noise from the neighbours but other than that I had some of the best sleep I've ever had in Rome. The kitchen and bathroom don't have heaters, but they were still not too cold even in the middle of winter, and the bedroom has an aircon heater that works very well.
I will probably stay in this apartment again when I'm back in Rome, I really liked it! Thank you
