Monti-Colosseo is 100% recommendable. Situated between Basilica di Santa Maria Maggiore and Cavour (Metro), it is located in a walking distance from all the touristic places, in a quite street. Big king size bed, the bathroom is perfect (great shower with great hot woter, also the hairdryer is a plus), big sitting room with a nice table and confy couch and small but perfectly functional and fully equipped kitchen. Also there were a couple of 'minimarkets' (grocery shops) around, a bit expensives but usefull for buying some food. This is a perfect choice!
