We had a great time in Rome and Luigi's apartment was perfectly situated to help us see most of Rome.
The loft apartment had one bed upstairs and two sofa beds on the first floor. We had a family of five and it fit us fine.
By far the most amazing aspect was the location. Luigi's beautiful apartment is on Via Della Scala which is a lively street with small shops, restaurants and bars nearby without being wildly loud. We literally woke up each morning, went downstairs and enjoyed really good coffee at the Caffe della Scala (next door). In the evenings we were able to have dinner at a couple of restaurants a couple blocks down (less than 5 min walk). Keep in mind, La Prosciutteria and Dar Poeta alla Scala is literally across the street (eg, 5 steps from the front door) and have amazing charcuterie and pizza respectively.
We could not have been happier with our stay and the location of Luigi's place was perfect.
