Roman Arabesque is a nice little apartment in the north-center of Rome. It's comfy, cozy, rather cheap, and well connected with the transportation of the city.
Rola & Claudio provides everything is needed, towels, hair-dryer, basic food (salt, oil etc), pots and plates in the kitchen. They live next door so it's easy to find them if there is any problem.
You will may hear their kids playing and chatting loud during the day if you stay in, but it's not that annoying anyway.
Highly recommended
