I am new at Airbnb (first experience). I spent three nights at Maged's place and it was good, very good.
Location - roughly 20 minutes by metro to the Piazza del Duomo - is excellent. Very easy to get there from the airport, especially with the lightning fast directions Maged sent me! The neighborhood is quiet (August in Milan is vacation time so many people are out) and the apartment itself is quiet. There are a couple of supermarkets nearby - one is in a mall so you can go there and get whatever else you need (even a haircut!) and see and experience italian daily life. There's also quite the open spaces around the place so if you go out for a walk or run it can be done.
Room is simple, but enough for a big double bed (Queen size probably) and plenty of space for clothes. Plus a table and a chair. Good internet, so if you need to do some work from there it can be done with no problems.
With regards to Maged as host I knew it would be good when I got the directions to get to his place faster than I can copy and paste to find them myself! Perhaps the best way to define him as host is what I told him when I left: if i'm back in Milan I'll check out with him first!
Thanks!
