This is smaller, but very convenient place, it has everything you need, the host even provides a coffee capsules and some croissants, replies quickly, helps with everything and is overall very kind. Also, after we checked out, we could leave the baggage in the building and reclaim it later when we returned, so we didn't have to carry it around Milan!
Don't let yourself be scared by the look of the building and it's inner court, the apartment itself is brand new, clean and air conditioned.
The location is very convenient for travelling from/to Milano Centrale, as it's less than 5 minute walk.
