This apartment is huge, elegantly appointed, and in the best location in Rome. From here one can walk anywhere one might want to go. It also has a spectacular terrace. My family spent a week here at Christmas, with adult children and their spouses. There are several things to know that make it quirky, which do not come through in the listing, however. One is that the apartment is on 2 floors, the living space connected to the bedroom area by spiral staircases that are poorly lit and without handrails. These stairs are daunting. Another is that the master bedroom has no windows. In order to get any light or air, one has to leave open the connecting door to the atrium sitting room, thereby giving up privacy. Though there are 3 bedrooms, they are uneven in scope--2 large, one small with a window overlooking an open shaft where the neighbors throw out their garbage early in the morning. The sound of crashing bottles woke my daughter and her husband on several occasions. There are also two entrances, for which you are given 2 sets of keys to each, even if you are 3 couples. One is a straightforward door to the elevator landing, leading to a set of doors to the street. The other, however, feels a bit like a trip to Narnia: down an open, narrow, spiral staircase to a hall with a poorly-lit door leading to another door to the courtyard of the building, all of which must be carefully double-locked/unlocked. Whew!
One should also know that Elena, the housekeeper lauded in many reviews, is gone. There is now a very nice couple on staff living in the apartment with you. They try to be unobtrusive, but, for example, you are still sharing "your" kitchen with these nice people, who nevertheless are strangers. (This may not appeal to everyone.) They make the beds and lay the table for breakfast, but are there really to ensure that nothing goes wrong, which could, of course, be helpful if something did.
Although the apartment is clean, be aware that nothing is new. The bathrooms, the kitchen, etc. were renovated decades ago, which was fine with us, but may not be fine for everyone. All in all, much as I loved the location (and I do!), size, and elegance of the apartment, I wish I could rate it "excellent", but I can honestly only go as far as "good."
