Room was average by Japanese standards (i.e. small by American standards), frosted window so no view, but otherwise just fine. I liked the keypad for room entry, no way to forget your key card (but definitely take a pic of your entry code). Lobby is a bit small for breakfast but it works. It was cool that they mixed up the breakfast options despite being a fairly budget hotel. Oh, and free booze for cocktail hour?! Amazing.
Another reviewer mentioned the pillow situation. There's like a pillow *library* right in front of you when you walk in, so it's hard to miss. You'll definitely want one, though, as the default pillow is quite, shall way say, firm.
It's a short walk from the northernmost exit from Ueno Station, but it's really close to the overpass into the park and the museums. Definitely easy to walk to all the stuff in the Ueno area, though it is a bit of a schlep to the Keisei line entrance (which is the best way to get to Narita), so maybe a bit of a tradeoff.
