Our stay in Roberto's flat was very nice!
The location is perfect - exactly next to Via Maqueda, so anytime you crave an arancini - just go outside of the flat and get some! Or if you need to reach any of the main attractions, then it is very easy to navigate from here.
Even though this was a separate room in the apartment, not the whole apartment itself, you had a key to your own room which is good and safe!
The room and the flat itself was very clean and communication with host - very fast and efficient.
Don't make the same mistake as we did with getting some food from the store for your breakfast and such - you will end up realizing that the street food costs the same (meaning - cheap! :) ) and you will anyhow overeat on it and end up thinking about how to finish the food from the store! :D
