We stayed at Elisa's apartment for almost a week and it was absolutely perfect. I can't think of a better location in Rome, in walking distance from everything, just between the Spanish Steps and Piazza Popolo, and right near the Borghese Gardens. It's such a beautiful old building, high ceilings, marble and tiled floors, great little kitchen (with everything you need) and gorgeous terrace to relax in the sun or have a meal on. I would not hesitate to stay again next time I'm in Rome!
