This is an excellent place. Superb loaction. You can take a train to Vatican (Cost only EUR1) and you can take tram No.8 to Victor Emmanuelle (for visiting Collosseum, Trevi fountain and etc.). Also, it is also close to supermarket.
The room provides adequate equipments; fridge, cooker, washing machine and etc.
Only one small weakness is that the room is on the basement. There is little light come in which causes a lot of humidity. Nevertheless, it is not a big deal since we spent most of the time outside.
In overall, hightly recommend to those who is planning to visit Rome for few days.
