Xiuping was very friendly and welcoming.
Apartment has everything you need.
The apartment itself has a great location (bit less than 20 minutes from Coliseum, by feet) also near 2 metro station stops.
The Termini district might feel a little unsafe at night, but I didn't have any actual bad experience there. :)
A few times it was a bit loud after 10-11PM.
Other than that it's a good option for one person.
