Carlo was very welcoming and explained how the apartment worked. There are pros and cons to this place. The location is excellent, 3min walk from Piazza Navona, 10min walk from Vatican. Neighborhood is artsy, with shops, artist studios, a market, restaurants.

Cons: extremely noisy from the street and restaurants, couldn't sleep. There isn't a proper shower in the bathroom, just a cage that you wrap around yourself and the water drains into the floor; no proper bed, it's just a fold-out futon; no proper kitchen, the sink is tiny and there's just a hot plate for heating--and hardly any useful utensils like plates, bowls, etc.

In the end, the place wasn't too comfortable because it was just inconvenient to use anything (bathroom, kitchen, bed) and it was too noisy.
