The only thing good about the place is it being close to Ueno Station, and plenty of izikayas and restaurants. The place is pretty disgusting! I'm no snob, and have travelled alot in the past 20 years, but here was something else. It's dirty, smelly, run down, and hasn't been cleaned properly in years. When it came to using the bathrooms I hated putting on the filthy sandals, and restored to the using the toilet a la Finch from American Pie.
I requested a non-smoking capsule but at the end of the corridor was the smoking area so everything and everywhere smelt of cigarette smoke. Then there's the taps - I used bottled water to brush my teeth as I didn't want the water from the dirty taps coming into contact with my mouth!
The sleeping capsule itself was stained yellow through nicotine, and there was a couple of ominous looking brown marks on the inside of the curtains, as well as dirt on the mirror. And to top it off the music (well, one song), a Spanish guitar style elevator tune, played in the reception/shower/locker area is on constant repeat, like some hellish groundhog say nightmare. I've complained to Hotels.com but have yet to receive a response. Classic.
If I could have found somewhere else to stay on discovering how disgusting it is I would have, but alas it was a public holiday and most accommodation, aside 5* hotels, was booked up. It's not even cheap to stay!
