What an amazing place to stay!
It's right in the middle of the heart of Colonna, but if you close the windows the appartment is very well soundproofed. Public transport is also close by, but I reccomend visit everything on foot. The place is clean, thoughtfully designed, and large enough for quite some time in Rome. The balcony is big and delightful, it’s a perfect place to chill out and have an Aperitivo before you go out for dinner. Our host went above and beyond to make everything as easy as possible for us, we get many advices and suggestions about places, shops and restaurants.
We loved every second at this apartment and hope to be back one day.
