The flat was clean, well equipped and stylishly decorated, and the location was great - handy for the metro, local shops, cafes and restaurants, and for the Pinoteca di Brera.
However, the flat is directly above a very noisy bar, so unless you're a heavy sleeper, or a night owl, this flat won't be for you.
Finally, this is clearly a commercial business and there seemed to be little goodwill. We were charged extra for using both bedrooms (we had to pay for three guests even though there were only two of us) and there was a 20euro charge for leaving a bag beyond the 10.30 checkout time. All of which left a nasty taste.
We won't be returning to this Airbnb, but will be back to the Brera as soon as we possibly can - we loved the area and the city.
