As the previous reviewer writes "this proprty exceeds this brands standards" and I definitely agree. Having stayed at Marriott Residence Inn's across the country - this is probably one of the nicer properties. The front desk is friendly and helpful. The lobby is warm and inviting and has a great complimentary breafkast on weekends and weekedays - that actually goes until 10 am - so you can sleep in, should you want. The rooms are impeccable - modern, up-to-date and clean. They are also much bigger than the typical Residence Inn properties and have all the amenities that you would expect. My only problem with these properties is the hair dryer - - it should be a much better one given the property - a very minor touch - but something that should not be overlooked.
Overall - this is one of the nicest / if not the nicest places to stay in Duluth. I highly recommend!
