Reading a couple of the negative reviews, I guess I just have to say that anyone, any hotel, can have a bad day. This place is in my top five favorite Marriotts I've stayed in - and I've stayed in a lot of 'em.
First, it's nearly new, and everything is in Marriott's new style: dark wood, lots of contemporary features, etc. Yet, they've managed to keep the 'old school' feel of the building they repurposed. Let's be clear, though - this was no remodel. Despite the age of the original building, everything is completely new here.
While I didn't eat at the restaurant, I did enjoy a couple of cocktails with Pat, the bartender, who was a wonderfully affable dude. He knows his stuff, and he was delightful to chat with.
The coolest part of my short visit was the executive lounge on the 2nd floor. As you exit the elevators, the lounge is at the end of a long hallway (think of the TV show "Get Smart" if you're old enough to remember) with two towering doors at the entrance. Using the key card to enter, the doors unlock like a huge safe, allowing entry. Sweet! Once inside, the food was plentiful and great.
Try this place. It's positioned to be a big part of Milwaukee's resurgent downtown - and you'll love it, too!
