Well worth a visit to the Maxxi in Rome for the architecture, the quirky offbeat exhibits (some that will inspire, some that will educate and some you will wonder why) and for the peaceful and reflective space that is the Maxxi and it's grounds. It is a very short tram ride from the via del corso and takes you away from all the crowds into the more peaceful 1960 Olympic village. Apart from the Maxxi, which has cafes and a restaurant, there is the Olympic architecture, the auditorium and great local cafes and bars.

It was great to see a modern alternative to Roma's ancient history. The building itself is well worth the visit for the architecture, stunning interiors and interesting modern art and architectural exhibitions. The Maxxi is located in an area with other attractions close by, for example, the Renzo Piano designed Auditorium Parco Della Musica, Pier Luigi Nervi's 1960's Palazzetto dello Sport (which was part of the Olympic Village), the contemporary Ponte Della Musica by Buro Happold Engineering and the historical Ponte Milvio with it's infamous padlocks that couples lock onto the lamp posts to show their love for each other throwing the key into the river. After seeing these sites there is a wonderful contemporary bar called the Tree Bar on Via Flaminio and many restaurants nearby along the Viale Vignola and surrounding streets.

Among others museums in Rome with contemporary and modern art, MAXXI is the most expensive and the most distant from the city center. The architecture of the building is innovative and fascinating. Unfortunately it is the only thing worth visiting. Once we were in, we realized there was barely nothing to see and whatever we saw does not deserve being called art.

I've seen that some people here on Tripadvisor gave this museum a negative rating.
I found it wonderful, but I can see that you might find some things a bit inconvenient. In comparison to the size of the building, it has few exhibits, it is off the beaten track and it is quite expensive, although I personally used one of my two free tiquets of the Roma Pass.
But for me it was just perfect, because I stayed a whole week in Rome and at that point was totally sick of the heat, the masses of people and also of Roman ruins.
The MAXXI was cool, quiet, spacious and empty, which was just what I needed. The building is beautiful and I found the pieces of the exhibition quite stimulating and inspiring, although I'm not a conoisseur. My host also recommended the bar inside, although in the end I did not check it out.
The MAXXI can be reached easily by tram from Piazza Flaminio.
