Great location just outside of Piazza de Popolo at Northern side of Rome. Easy to get to central areas though driving is awkward cos of all one way streets. Apartment is bright and spacious and Donatella has a lovely fridge full of welcoming goodies to set you up for your stay. There is a supermarket just around the corner.
Easy access to Tiber and then to Vatican. On edge of Borghese Gardens too. Would highly recommend.
