My candid review of this hotel...very poor!!!
Let me first start off my saying that I have stayed at this hotel approximately 11 times (2-3 night stays) since Dec. The reason why this hotel was chosen is because of its close location to the Animal Medical Center next door of which I visit for work frequently. I am a business traveller and I do not usually complain about hotels but I feel it my duty in this case to share my experiences bullet pointed below....
Rooftop Restaurant and Room Service-
Restaurant has a beautiful wrap around deck of which you can see great views of the city. Unfortunately I saw two cockroaches(quite large) walking around on the deck, The deck is very close to the kitchen.Room service is extremely slow,this week it took one hour and 15 min for delivery. I was told they are short-staffed. This seems to have been the case on several other hotel visits. Also I have complained several times that I can't get a hold of anyone to even call for room service. They just don't pick up the phone. I have never had food delivered with a salt and pepper shaker which may sound trivial but it is pretty standard in most hotels. One time I asked for a side of rolls...I was told rudely "we don't have rolls" which again I find odd. On another occasion I ordered grilled chicken. It came down from the restaurant through the elevator (which was full of people) unwrapped, no covering at all. 
Front Desk-
The attendants at the front desk are very slow although Alex does a great job of greeting people. They just don't seem to be organized and their computers are always very slow. At night the front desk attendants are rude and disorganized. I have walked by and there always seems to be an "issue" being discussed regarding an upset customer.
Rooms-
Bathroom is full of black mold along the edges of the tub. Have they ever heard of using TILEX?? The showers are very odd, in order to turn the shower on you have to reach in and turn the faucet on and then pull up on a lever,you will get wet with cold water if you don't back off quickly. Because there is only half glass in the shower to keep the water out the floor gets soaked, it is aweful to step out of the shower and have a 1/2 inch of water on the floor.
On this last trip I was given room 203. The air conditioning did not work so I was switched to room 207. On the second night I heard water dripping and I had streams of water flowing down the window from the insides of the ceiling. I called the front desk and was told that a water main broke. I asked to be switched to a new room but they only had smoking rooms available which are disgusting. I went to the front desk and they were going to move me to another hotel....it took and hour and a half for this to be resolved. The attendants were at the front desk on the phone and were less than helpful in getting this resolved quickly....the general Manager showed up and I was comped one night.
Internet access...forget it...even a wireless card does not work in the hotel.
Lamps in room are broken,furniture is all scrached near the bed and not all rooms have bedside clocks(room 207).Outlets don't all work.During one of my trips my blow dryer turned red hot and smoked. When I called the front desk I was told that "they have no blow dryers" available in the hotel. I had to wait until someone checked out before I could get a blow dryer.
It seems to me that a hotel like the Bentley should have back-up supplies for the room.Co-workers who have stayed at the hotel with me told me that they either had rusty dirty water or no water in the bathroom. I have not personally experienced this.
As far as the rooms, expect a very noisy stay. On two occasions I could hear crystal clear the "activities" of a couple next door throughout the night and morning. This may not be a good place for kids.The building also has odd noises depending on which room you are in...cracking sounds,friction sounds from inside the building...maybe it is because the building is so old.
Elevators are extremely slow...expect to wait 7-8 minutes to catch one in the morning...stay on the 2nd floor if you want to avoid this and take the stairs. Two trips ago the power wnet out in my room (Only my room)...maintenance had to come down and reset the switch!!!!
I am sure that there are some items I am missing. I am disappointed that I have had this many bad experiences but as I said it is the location only that keeps me coming back due to my work location next door. I may opt to take a taxi from another hotel next time around....
