I had a pleasant stay at Marisa's place. Marisa and her husband were very welcoming. Their apartment is conveniently located in just a few blocks from the Colosseum and a block from the metro. Lots of restaurants, shops, bars, churches... at a walking distance. At times, it can get noisy from the nightlife in Rome but not a big deal. The room was nice and clean with a private bathroom. They provided a nice breakfast and afternoon tea. I would definitely come back.
