General Summary
Whether your comfortable here depends on what you want out of a hotel. Rex Milano is basic, really basic. From the bare bones breakfast offerings of croissants, cereal and coffee to the rooms sparse furnishings and small LCD TV. If your plans for the hotel extend beyond sleep and showers then I would look elsewhere. However if, like me, your traveling solo and just looking for somewhere simple to collapse at the end of the day the place is clean and the staff is friendly and helpful. Overall Rex Milano is serviceable.
A Few Specifics
Wifi is a paid additional extra. 6 euros buys you 2 days but the connection is god awful and only works half the time and then at a snails pace. Tip for the hotel - Move over to a dual band 2.4Ghz / 5Ghz setup, there are no devices operating at 5Ghz in the area and 2.4 is overflowing. You've also got all your access points on 11 along with many other APs in the area, the cross talk is causing mass dropping of packets which in turn makes the wi fi unusable. Wifi is important to people these days get someone who knows what they are doing to redo your setup.
I can't say I was comfortable in the area past 8-9 o'clock.
Good pizza place just 2 minutes walk away. Come out the hotel to the main road take a left and it is opposite the set of traffic lights. They speak english.
You can come an go via the Corvetto metro stop. 5-10 minutes walk away, with connections to both Centrale and Doumo.
Shower head was broken.
