This is a wonderful place to stay!
My wife and I have been to Rome many times, but this was our first time bringing our two children, ages 12 and 9, and we all had a great time!
Paradiso loft is like a 5 minute walk to many of Rome's most famous places, like the Pantheon, Campo de Fiori, Piazza navona, the Vittoriano, and many grest churches, and is 10 or 15 minutes walk to trevi fountain, Piazza di spagna, etc. The location was great for us, because our kids could walk to so many places.
If you stay here you must eat at the restaurant downstairs. The fiid is fabulous, which is really saying something for being in rome. The people who run the restaurant are so nice, and we felt like family every time we came back from an outing.
The only thing to consider is the Paradiso Loft has many steps, so this may be difficult for small children, or older peogle. However, this was no problem for us, or our kids.
Laura, the owner, was very helpful and easy to work with. She helped us get from the airport to the apartment by arranging a driver to pick us up at fiumincino.
I highly recommend this place to stay!
