We’re definitely positive about Xiuyings place:
It’s very clean and the Xiuying and her family are very nice.
Xiuying communicates thoroughly about the location, so it’s a piece of cake to find it.
I wouldn’t call the area residential as it is close to the station, but I do consider this a plus since you can easily go on foot from the station (Termini) to Xiuyings house. I would recommend this place; whether you want to visit Rome are if you’re just passing through (as we did - on our way to Naples). Thank you Xiuying!
