Location is one of the best in Rome. It was very close to everything we needed. We did the Vatican and Colosseum tours and they were easily accessible by foot in about 25 minutes. Everything else Piazza Novana, Trevi, Spanish steps were 5-15 mins away. I love the market right outside your door. We were able to start our day with a nice cappuccino and croissant from the little shops nearby.
You’re Very close to catching the bus to the train station if you need and easy enough to take a cab anywhere (we used mytaxi app as it was cheaper than Uber)
The only issue we had was the heat didn’t work so it was pretty cold at night and because the building is older you could hear everything from the apartment upstairs and outside. It made for a rough first night as it got pretty loud. We had ear plugs that seem to do the trick. :) the apparent was very clean as well!!
