The 'Lush' apartment is fantastic. I shared with two of my colleagues so having three large rooms and two bathrooms was perfect. The flat is enormous with a decent sized kitchen and a huge, open plan living/dining room. The whole place has a lovely flow and is bright and spacious.
There are a couple of balconies with floor to ceiling windows throughout the main living space which is perfect whatever the weather (we had everything from torrential rain to 25 degrees and all day sunshine).
The check in and out process was really easy, the hosts were communicative and helpful without being bothersome.
I cannot recommend this apartment enough - especially if you need to be near Tortona (for Milan Design Week). But shush... don't tell anyone... as I want to book it again for next year ;)
