This hotel is nothing special but I thought it was a relatively good value for Tokyo, especially since the rate we booked included wifi access and buffet breakfast. We were very satisfied here.
We arrived quite early, around 9 am, planning to store our luggage and continue on for the day's touring. Surprisingly, they said the room was ready and we could check in without a fee, so that was a pleasant surprise. The room was fine, not huge but decent sized for Tokyo and with good light and a nice view of the river and a portion of the Hama Rikyu gardens There was sufficient couter space in the bathroom, a large shower and the usual good array of toiletries and nightwear.
Breakfast got a bit crowded, but the layout of the breakfast room minimizes the scrum feel unless you're seated right by the buffet tables. The selection of breakfast items was good - one table of salad, one of Japanese items, one of breads, one of Western eggs and bacon, etc. There are made-to-order eggs and a coffee machine you can use to make lattes.
The location is convenient to both the subway and the JR trains, and an easy walk from Tsukiji fish market and the aforementioned Hama Rikyu gardens. You can catch a boat from the gardens up to the Asakusa neighborhood, then take the subway back. That being said, the location was a litle weird because the hotel is in an office building in the middle of an office park area. Fortunately, there are quite a few restaurants around the nearby train stations, but the immediate area was pretty deserted on the weekend.
