We were very pleased with this apartment. Although we are one family we had two couples and 2 singles and the apartment is very well set up to allow each to have their own space. Each bedroom has it's own bathroom (0ne is in the hall) and regulated air conditioning unit (very handy in July). The place was immaculately clean. The location was also excellent. A block and a half from the Metro, 2 blocks from a large taxi stand, 3 blocks from an outstanding open air food market (you just have to see it to appreciate it), three major bus thoroughfares within 3 blocks, tons of those cafe's, markets etc that Italy is known for and of course the Vatican practically next door.
The only drawbacks are the common area is a bit small. We knew that going in so it wasn't a disappointment. But if you have a lot of people in your group, the dining area and kitchen are limited in space. There is place to sit for each but it's not lounge around friendly - but when in Rome why stay indoors. The internet router is a bit limited in its coverage of the apartment. The service is not spotty, it's just at both ends of the apartment the signal is weak.
All in all, I would stay here again without a doubt and highly recommend to groups of folks with sub groups that like to have a separate space at times.
