This Airbnb is an a brilliant location and is very well-equipped, more of a studio flat than a room - it is ideal for a single traveller (or a couple who *really* like each other. So much of Milan is within walking distance yet you can step away from the crowds and feel very insulated from them.
My one slight caveat would be that there is building work going on at this very elegant apartment buildng for the next year or so and the noise did mean I didn't get a lie-in and made it difficult to work in my room - so, if that's something that's likely to bother you, ask which part of the building that the team are working on during your stay.
