Spacious flat in a very central location. It's a bit more lived in than looks in the photos, and has a bit student vibe rather than designer. However, very well located, close to metro, Duomo and easy to find a taxi in the Duomo taxi rink. If you come with car, there's a parking garage around the corner.
Very comfortable and big bed! During the weekend the bar downstairs is a bit noisy, but it didn't bother our sleep. The flat is on 4th floor (there's a lift though, don't worry) so, sun fills the living room in the morning, which is very nice.
Internet works great if you are on a work trip.
Bathroom is spacious, but the shower is small if you are tall.
We booked last minute and the communication was great. Analyse the check in video to find the lock box - it's not next to the flat.
Overall, the flat was a good base to explore Milano!
