On paper this hotel is excellent. Modern, good location, views of the city and complimentary breakfast. Some comments:
1. The staff are not particularly friendly or welcoming. There are about 12 floors of serviced apartments, perhaps this is why it doesn't really "feel" like a hotel in which you are a valued guest? The decor and atmosphere is pretty sterile.
2. The "breakfast" was astonishing in its lack of choice. It's almost not worth getting out of bed for a few paltry pieces of toast and a grim coffee served in a soulless cafeteria. Would rather they just knock the 300 yen (or whatever they charge any non-guests insane enough to pay) off the room rate and send us to the acceptable Italian restaurant just around the corner.
3. We stayed 2 nights: on Day 1 the room was cleaned at 5pm (even though we were out of the room at 10am). I thought this should have been done earlier - by 5pm I wanted to be back in the hotel for a mong-out, shower and to get ready for evening pursuits. Minor, but since there is absolutely nothing to do in the hotel, was just loitering outside the room for 40 minutes whilst they cleaned it.
4. View was OK, weather was rather poor so unlike all the other reviewers I didn't catch a glimpse of Mt. Fuji.
5. Room was decent/modern, though bathroom was dated, cheap and the bath leaked.
Would not stay again for these reasons.
