It was a large apparent (3 rooms) converted into small apt (1 room) for rent (no kitchen!), located on the 3rd floor - building as has a lift.
Room very spacious, clean, modern. It had small fridge, nespresso machine and kettle.
Only thing we were missing there was the cabinet for clothes so we had to keep them in our cases but there were plenty hangers for clothes.
Very quiet area with nice pizzeria on the corner (Foodisfaction) and 2 coffeehouses in the same building. Walking distance to city center, Spanish Steps (15min), Colosseum (35min), Roma Termini (15min).
It was so convenient location that we haven't used public transport at all - only to get to the airport.
It has a quite early check out time 10:30 but we were able to leave our luggage and have it collected later during the day.
We have spent great time there and if back in Rome that would be our first choice to consider.
