I booked a hotel room for 4 nights at this hotel through an online vendor. After booking the hotel room I contacted the hotel to request a room with 2 beds. I was told in 3 different conversations with hotel personnel that I would have a room with 2 double beds. When I arrived I was given a King sized bed and was told that there was nothing the hotel could do for myself and my 3 guests. Apparently the hotel management saw no problem with 4 people sleeping in 1 bed. The staff was completely unaccomodating. To add insult to injury we met other guests that had obtained a room with 2 beds by just walking in off the street the day after we checked in. I would not recommend this hotel to anyone. The customer service is well below what is acceptable. The location of the hotel is great but there are many other hotels that offer excellent service and high quality rooms to stay in while visiting Chicago. Bottom line is do NOT stay at the Millenium Knickerbocker!!!

Here are my experiences: - Had three rooms reserved, when checked in we were charged 2 different rates for the rooms - screwed up initial room assignments, gave us a room that was not even cleaned yet when we checked in - Could not get us new keys to a different room without great difficulty (we had to go to the front desk because bell staff went to the wrong room to give us new keys) - In room guide says pool in on the 8th floor and signs say it is on the 7th - could not get to the pool from the 14th floor without going all the way down to the lobby and then had to go to the 7th floor and take the stairs to the 8th - When we checked in we had the front desk staff go over which credit cards were assigned to which room. - When we received our bills, the credit card assignments were still wrong. I stay at "economy" hotels a lot and I have not even come close to having this many problems with a hotel until this one. This hotel should do Chicago a service and just close its doors. Due to this experience, I will never stay downtown again to deal with overpriced hotels with poor service and surrounding business that are just as bad.

When my husband and I went to Amalfi Hotel we were expecting first class service. First, when we got there we learned they had given our room to another guest and we were not able to get a suite like we had booked. Room service took forever and the food was subpar. Supposedly they had planners to help explore the area, but we requested one and never saw hide nor hair of a planner. The spa staff seemed incompetent. The only positive things I can say about Amalfi Hotel was that the rooms were stylish as advertised. I give this hotel two stars.
