Overall, the apartment was very nice and spacious. I was travelling alone, but the two washrooms would be excellent for more people. The living room and main bedroom were also large. The laundry machine and dishwasher were also convenient.
I prefer less busy and more artsy neighbourhoods, but that’s my personal style. Still, the apartment is very conveniently located, immediately next to the metro/subway, close to the park, and next to a famous piazza and fashionable district.
Not many apartments have elevators, but this one does, so that’s a big plus. I usually try to take the stairs to walk off some calories, but one word of warning: the marble on the stairs is very smooth and slippery even when dry; I fell twice wearing good running shoes, so I stopped using the stairs; this is not the Host’s fault at all, but it might be safer to just use the elevator, which comes very quickly.
As a couple others mentioned, the only thing that could bring it to the next level are some extra small touches to make the guest feel more at home.
