The flat is everything you expect. It is super clean and cozy, and because of the self check-in, you can arrive at (almost) any time you want. It's not that close to the city center, but you can easily walk (+- 30 min) or use public transport. Plus: the hosts even provided some breakfast!
Talking about the hosts: they are super friendly and are very easy to communicate with. They suggested some great places to have dinner in the neighborhoud, so don't hesitate to ask them for advice! (Although I can only assume they were great, we never got in because they were completely full all the time... ;) )
I would definitely reccomend this place for your stay in Milano!
