Lele's apartment in Monti was a meaningful part of our Rome experience. As you go up the stairway (pretty steep stairs - but you get used to it) , when you enter the apartment and walk unto the terrace, the atmosphere of Rome stays with you. It is exactly what you see in the pictures, but the feeling of the Rome "magic" can only really be felt when you are there.
The apartment is in a wonderful location for touring the city - in walking distance to many sites, especially the Colosseum, but there is also lots of public transportation in the surrounding streets . In the evening, especially on the weekends, it fills up with young people who come to enjoy the restaurants and bars. There is a bit of street noise because of this, but at least for me (and I am a light sleeper) it did not impose a problem.
Our communication with Lele was very good. We were met on our arrival by Andrea, who was right on time. This is important since there is no lobby, like in a hotel. He helped us up the stairs with our luggage, got us acquainted with the apartment and the area, and answered all our questions.
I can only recommend this apartment and will certainly come back when in Rome again.
