We, 3 people, had a lovely stay at this apartment!
It is very open, bright, has a nice kitchen and the terrace was so lovely. Very nice sitting there in the sun and enjoying the view of the river. The bathroom was big and modern.
Be aware. You maybe have to buy dish cloth, dishtowel, paper towel and toilet paper when arriving. There wasn't any of the above when we arrived.
The kitchen was modern but there was only one knife and no cutting board. So, sadly, I would not say you could make a proper meal.
There is a fair share of dining places in the area which was nice coming home from a long day of sightseeing.
The hosts were very nice and quick to help with questions concerning supermarkets, luggage storage ect.
All in all I would definitely rent this apartment again if I ever come back to Rome.
