We will come back again. Elena's place is located centrally and close to everything. There are so many place for food (pizza, pasta, dessert, pastry, etc.) right downstairs. Elena's apartment is also vert well stocked (e.g., enough dishes, glasses, utensils, etc.), and we felt right at home right away. This is very important for us because we have two young kids (7 and 4). Oh, and there is also a washer, which is also super important for us because of the kids.
We will definitely try to book again next time when we visit Rome. Strongest recommendation to fellow travelers.
