This cannot be written quickly. Some things on the hotels.com web site were not so clear, but I booked because of the high user rating. First: it is not that easy to find, unless you know there is no sign. This is a B&B in a larger apartment building. Simply get to Scanderbeg Piazza and look for the number inscribed in the walls of the buildings. On the correct building there is a pad with 10 or so push buttons, and the one labeled Domus Trevi is the one you need. The rooms are on the third floor, but there is an elevator (very small) that you have to take to the fourth floor then walk back to the third to access the rooms. The breakfast is not a large spread but it is fresh and adequate. The rooms are small but adequate. So why the rating? One word (actually a name): Raluca. This wonderful gift to travelers is unlike anything I ever saw. She is smart, efficient, fun, informative, helpful. She is the manager, housemother, concierge, chef, mother confessor, guardian angel, and so much more. Simply tell her what you need and she makes it happen. If there is something you need to know, she will know it. She makes you feel as though you are family. I simply cannot say enough about her. Honestly, I would return to Rome just to sit and talk with her. The property is about a minute's walk for Trevi Fountain, and there are shops - and hucksters - even closer. There is a fine little restaurant right next door, and gift shops, gelaterias, pizzerias, etc close.
