This is a great apartment located in a residential part of town. It is very convenient to public transport and Uber is also pretty readily available. We had no difficulty getting to all of the major attractions in Rome. It is also very close to Piazza Popolo which is not on most tourist's lists of places to go, but it is a great gem.
I have stayed in many AirBNBs around Europe and Cristina's apartment on Via Girolamo da Carpi is one of the best and Cristina is absolutely one of the best hostess's I have encountered.
