Very central location in the middle of Rome, with walking distance to everything.
It's a clean good place to stay, with good beds, and a good bathroom to every room. But do expect to throw used toiletpaper in a bin, because of old plumming. Also a warning; they charge an extra 3.50euro per person per night, collected in cash, for the City Tax.
This is not a normal private apartment you rent while the owner is away, it's a semi-professional bed&breakfast, without the breakfast. Just a big old Roman apartment, made into 4 rooms with beds and bathrooms. No kitchen, only small fridges, glasses and cups and etc.
The standard was ok, but loose sink in the bathroom with some leaking pipes, towel holders falling off the wall, doors to the rooms who didn't close from the (we fixed it applying some sunscreen as lubrication)....as you're there for the location, these things doesn't matter much.
Someone (usually) comes and cleans the bathroom between 10-12, which can be nice, but you also have to relate to that, which you don't do in a completely private flat.
Also, when we returned from breakfast one day, some unknown people had been locked into our rooms, with the "host-assistent", to have a look, without noticing us. Apparently some interested buyers. Very unprofessional and unpleasant, as we had all our stuff laying around. I'm glad it was us grownups who went up, and not the young kids who went home alone.
In summary; not a hotel-experience, and not the private-home-in-Rome-experience, but good beds in a very central location!
Also good fast communication with the owner/host!
