Our host Nina and her place are so wonderful! Nina herself is very responsible and always reply message almost instantly, and despite our delay in our train to Rome, Nina was very understanding and welcomed us to her lovely flat. To be honest, my friends and I did not expect much originally due to the low price, and turns out the place is neat and tidy, every little details were well designed. And there was one day where we ran out of tissue rolls but since it was quite late at night the supermarket was already closed, we messaged Nina intended to ask for more the next day, but Nina immediately replied she would come in one hour and She DID! As for the location of the flat, almost all of the famous tourist sites (Colosseo etc,) are in walkable distance from the flat. We couldn't recommend Nina's place higher!
