This is our second time with AirBNB and we weren't disappointed. The apartment was spotless and nicely furnished. Pina was very responsive and was waiting for us when we arrived, even though we missed our train due to severe delays in getting our SIM activated at the Vodaphone shop in Venice airport (don't use them!). It's an easy walk from the train and 15-20 minutes to the Colosseum by foot.
