Carla is an intelligent, thoughtful, and sentimental host that really cares about her guests. I could tell that she genuinely wants her guest, who's usually a tourist in Rome, to have the best experience and leave the city a happy guest and tourist. She took her time to advise me about all the tourist attractions and how to get about places. She's also a great conversationalist.
Now while her place is cozy and very homey, it is quite far from the city central. But if you don't mind taking an hour by train to get to the center, this place is a great location to interact with locals and see non-tourist side of Rome, which is great.
Overall, I recommend 100%.
