This was my experience staying at a Conrad hotel and I can honestly say that it was amazing. The location is very convenient for tourists and it's within walking distance of the fish market and even Ginza depending on your stamina.
My room was really sleek and stylish. I'm not sure what the square footage is, but the designer definitely made use of the space and it felt like I had a lot of room to walk around. There's also a comfortable wall-to-wall couch this is perfect for gazing out the window.
I also found the staff to be very friendly and accommodating. I arrived very tired and felt rundown after an intense week of of travel and they quickly put me at ease.
If you have time, sample a few of their specialty cocktails or dine at their Japanese restaurant.
