We're going to Rome in April, and are looking for a cheap B&B in a central location. We found this, B&B l'Archetto:

Does anyone have any experiences with this B&B? Any input is greatly appreciated!

Welcome to Fodor's.

I advise you to keep looking. The only thing that B&B is very close to is the train tracks. Not central and not a good location for a tourist.

The map on their website distorts the location too. Here's a better view.
Click "west" to see where it is in relation to the river:

what is considered cheap to you??? we rented an apartment in Trastevere (5 min walk to Forum) for about $115 a night. it was a full apartment complete with kitchen and extremely nice with all marble. also in a neighborhood setting. by having the kitchen we saved on breakfast and lunches out. it also had a washer/dryer. do a google search for rome apartment to rent and you'll get lots of hits. they are usually nicer than most hotels.

Kim, where did you get that apartment?
