We have just returned from a wonderful 5 night break in Rome staying at Giovanna's . The apartment is ideally situated for those who want to explore Rome on foot (the best way to see this wonderful, historic city) We walked to the Colosseum in about 15 minutes, Circus Maximus 25 minutes, Spanish Steps 30 minutes, but there is so much to stop and see these are approximate times. The Vatican and St Peter's is a little further away but easily walkable. There are also museums nearby and many more monuments and historical places in close proximity.
The apartment had everything we needed for our stay and the terrace was just fabulous with its views across the rooftops of Rome with St Peter's in the distance. There is a small supermarket a minute walk away, which is like a Tesco or Sainsbury's Local.
I would highly recommend Giovanna's for a stay in Rome for its excellent location and the terrace.
