I wanted to like this place—family-run, conveniently located near the train station, and including breakfast. In the end, however, it's hard to recommend Stella's House. The family is nice enough and the location is good, being easy walking distance from the train station (with its own connections to airports). Here is the breakdown of “however”:
Stella's House is actually a couple separate residences, in which members of the family live, so you are not getting a hotel room, but a room in a family's house. Although this, in itself, need not be a bad thing, we were led to the sister's house, where (as of Nov, 2011 at least) a toddler with some healthy lungs happens to live. We were woken up both our nights there by the kid screaming, followed each time by his mom screaming back at him. So there this noise factor.
Also, there is a second room let out to tourists, and you will be sharing a bathroom with them or, if they have been sold a “private bathroom,” you'll share with the mother and boisterous kid. Both bathrooms are not cleaned with any frequency or gusto. There's mold in showers and around sinks, and toilets are . . . well, we cleaned it before using it. Towels are so old & starched as to be abrasive—nice if you want to exfoliate yourself; also, of the two we were given, we only ended up using one for bathing purposes because the other stink, stank, stunk. We'd innocently dried our hands with it after washing them, and it left our hands smelling of mildew. Don't worry, we did wash our hands again.
There is no TV (yeah, that's what you came to Rome to do—sit in front of the Lobotomy Box), and no internet; this latter item was odd only because the brother told us that there was wireless access in the room and that no password was required and we hadn't even asked about internet. They may have decided that both TV and internet would be silly superfluous amenities, given the fact that there is a Triple-X movie theater immediately adjacent to Stella's House.
Breakfast is coffee and a couple of cheap, bland, packaged croissants.
So, if you have earplugs or don't mind familial yelling, can take a little mold, dirty toilets and mildew-ridden, sandpaper-like towels, you have found your place.
