My fiancé and I stayed 6 nights in Miriam's comfortable, beautiful flat near Trastevere. Miriam and her entire family were very accommodating throughout our stay. She met us promptly upon our arrival and even had a fluent English-speaking friend come by to help settle us in. She left all kinds of fruit, juice and snacks for us. We locked ourselves out one day and within a few minutes her mom and brother came by to help us get back in.
The flat is across the street from the Quattro Venti train station and was an easy transfer from the airport. The tram is also very close. The neighborhood is super charming and quiet, and we walked almost everywhere.
We highly recommend this flat to anyone and would love to stay again when in Roma!
