For me - it is the best place to stay in Rome. Ideal for many reasons:
1. Respectable, clean and quiet district. Your own entrance to loft and very delicate owner. All you need like clean shower, fast wi-fi, air condition, free maps of Rome and etc.
2. 5 minutes walk to main park in Rome - Borghese with all its flowers, architecture, fountains and so on. Right near the entrance to the park - playground for kids.
3. 5 minutes walk to National Gallery of Modern Art with Cezanne, Duchamp, Degas, Kandinsky, Mondrian, Monet, Pollock, Rodin, Van Gogh and ... very lovely cafe ;)
4. 15 minutes walk to Piazza del popolo, 20 to Spanish Steps and so on
5. 3 minutes walk to tram stop

So just book and joy! ;)
