I spent 3 weeks, alone, at Andrea’s place, and it worked perfect for me. I liked the best the location, a stone throw from most places you wish to visit, and even those that are more distant, with the vicinity of the Metropoliten and buses (easy to figure out which bus goes where!). Also, shops and a small covered market at Monti are all close. Another thing I appreciated a lot was a plentiful of sunshine, that is, natural light, provided by 2 large windows, precious in winter months, the apartment facing the south. Some might find the spiral staircase narrow, some might find steps difficult to climb, but that wasn’t an issue with me. I just was feeling like a local, living in my own place, not totally polished, but perfect in its little imperfections.
I would recommend the place for a couple, eventually for a couple and a younger child, a matter of intimacy.
