"Very pleasant stay!"

10.0

It seems like this hotel was recently added to the Marriott network and figured I'd check it out. From the beginning, the staff was extremely friendly and accommodating. I was upgraded to a corner suite being a titanium member with Marriott without even requesting it, and the room was great. I called about a couple decaf Nespresso pods pretty late night and the front desk had it delivered within a minute. Shower water pressure was top notch, and super quiet at night (aside from the street noise but typical with any hotel in the middle of the city). Location is also really good, sort of in between the mag mile area and river north. Will definitely be staying here again, so glad it's part of Marriott now!
