My husband and I were in Rome for the Marathon in March 2009. I found and booked this hotel after price comparing and reading reviews on here and elsewhere. The hotel is/was fairly difficult to find the first time. It's tucked between a couple cafes and you can walk right past it very easily... as we did the first time.
The hotel is pretty much bare bones and the photos on its website are NOT representative of what the rooms truly look like. There is a reception desk, elevator, room with a TEENY, TINY bathroom and shower (more about this later) and bed so close to the wall that my husband had to walk sideways to get from his side of the bed over to the bathroom, and that's about it. But really, when you're in Rome, you're not really going to spend all that much time in your room, so it was okay for us.
The bathroom, in particular, the shower. Oh my gosh. For the Americans out there, think of your bathtub at home... long and fairly wide. Now, think of splitting that into thirds lengthwise and one of those thirds is the shower at this hotel. There's no shower curtain, and you can't hang the shower head up, lest get water all over the vanity, so you'd literally have to squat down, get yourself wet, stand up and soap up, and squat back down to rinse off. I have to say, it was the worst shower I've ever taken, and I had to do it three days in a row. And if you wanted to take a bath (say, after a marathon), there was no way for it to happen... the tub is just way, way too short. No thanks!!
The pros of the hotel are of course its location. You're so close to a lot of the sites and it's really in a prime place. If you're looking for a hotel to just chill in your room (and why would you do this in Rome?!), this hotel is not for you. If you want to get out and explore, as long as you can overlook the shower issue, this hotel might be right for you.
