눉Busy street but it's expected when you want to stay at the apartment with good transport connection and windows have good isolation.
눇Very nice owner and staff. Very willing to help you with any question/issue, ready to recommend what to visit, what and where to eat. And do that in a number of languages, for instance, English and French.
At the hall you can catch one from many book guides for Rome which was very convenient for me. Also if it's raining you can take one from shared umbrellas.
Breakfast is ok too (but due to law they can not do any home made food, only bought staff).
Also there was hairdryer, iron, coffee machine, at shared kitchen there was a fridge where you can leave your food.
Close to the center of the city. It took us about 25 minutes to walk to the colosseum (and we don't know the city, get lost sometimes, and weren't in a hurry).
Near the metro station - you can easily get to any touristic spot from there. The good point it's one of stations that work till 23-30, while part of them in other parts of city work only till 23-00 (surprise! - we were caught by it once).
Street is busy but windows have pretty good isolation (mostly - if the sirens of ER or engine of motor bike work full sound it gets into room, of course).
Room is very clean and nice. Conditioning worked perfectly. Grocery and basically almost everything is near, including fresh fruits.
Corridors in the building very pleasant and clean, very safe area.
Oh, and the city view from the window is breathtaking.
In short, it's beautiful, we'd love to stay there again and would recommend it for sure.
