The unit is beautiful and spacious, and it feels like you are staying in a hotel suite. It is located only a few steps away from the Spanish Steps so there is a lot of foot traffic beginning mid-day, but it is still relatively peaceful in the mornings and at night. The metro station is a few minutes walk away so it is very convenient. If you are dragging a lot of luggage, keep in mind that the walk from the metro will mostly be cobbled stones, and in the afternoon you'll have to navigate through a lot of tour groups in the area. Someone met us for the check-in process and it was very easy to coordinate.
Amenities were great. Rome was the second leg of our trip, and we were able to do laundry here in order to pack lighter for our trip. We would definitely recommend staying here!
