Maybe an ok 3 star - not more
This hotel is such a disappointment. The rooms are ok, we have a Corner Queen with a great bed, nice bathroom but it's not a five star room experience, rather a 3 star+. The view is ok but not super impressive. The location is great, no doubt about it. 
Ok, hotel itself is nothing special at all and I've stayed at a quite a few. Now we have the service - hallelujah, TOTAL FAIL. Don't expect anything more than the ordinary. The staff is nice but not trained in a five star fashion, rather a two star.
Check in: I arrived by time for check in and had asked for a high floor room. I was told it was going to take an hour so I said ok. After 30 minutes i was told it was going to take 2 hours so I skipped the high floor. My girlfriend (who hade made the reservation) arrived in the evening. She was told the room was already occupied and then there was that little, but still clear, hint that maybe she was a call girl. No one said that but the way she was treated was to hear discriminating (here we have a woman who has travelled the world and never has experienced anything like that)
Getting an adapter: I had forgotten an adapter and asked for one. They were all occupied by guests I was told but "soon" I would get one. I had a board meeting and needed computer as well as mobile (which I explained) and needed power. If it was urgent I was asked to walk five blocks to buy one (It was snowstorm in NY this day) After two hours and several calls still no adapter. I was now running out of battery and had to stop the conf call. I was upset now and called back but no reaction. When I 15 min later was furious, called and asked them to send someone "to buy 20 adapters for the hotel and I pay for them" it was some action. First when I offered myself to buy for the hotel I got an adapter. Wow, what a five star treatment.......I was calm and really nice up until then.
The remote: After having to stop the board meeting due to no power I thought I watch some tv. does the remote work? Of course not.......and remember we're talking about a five star hotel
The hotel manager: I called the hotel manager but he didn't seem to care at all to be honest. 
The James is a hotel that can charge high prices just because their location. I can never ever recommend anyone to stay here unless you need to get really upset. It's an ok hotel but for the same money you can have a really really nice experience somewhere else
