I can't possibly tell anyone accurately how to get to the hotel from the Ueno station because we went out of our way to not cross the pedestrian bridge (too many stairs and too much sun). My suggestion is to come out of the main exit and head towards the street with the Nissay building and go down that street keeping the Nissay building on your right. The hotel is on the left on this street just past the first traffic light with a Lawson's next door. We asked a lot of people for help and everyone is very nice and polite even if they didn't know where our hotel was located. It's easy to get to Narita from Ueno station (about 45 mins for 2,400 yen or there is a slower train for 1,000 yen).
The hotel is sometimes a bit smoky in the lobby, but they do have one computer and the wi-fi also worked in our room (on the 2nd floor). They also have a massage chair for free. The room was incredibly small even for big city standards but was clean. They provide a small refrigerator, central A/C (not much way to adjust it), hairdryer, slippers, hot kettle/tea set, and kimono style robes. There is no storage or even a luggage rack only 4 hooks on the wall and a few clothes hangers. We requested a nonsmoking room and it smelled fine even though there was an ashtray on the desk. The TV had a few free channels but we didn't watch much. They give you toothbrush/paste in the bathroom and they had bath sponges and razors at the front desk.
There were a few maps in the lobby, but the best ones were the ones provided at the front desk when we checked in. You have to leave your key at the front desk when you leave which has to be used to manually lock your door.
The location was pretty good, but I think we could have found a hotel a little bit closer to the station. After a long day of walking the street seemed too long and the hotel very isolated but at least it was quiet. There are some great shops/restaurants a few blocks over from the hotel. You should try the octopus balls and get a shave ice. There are not very many tourist type shops in Ueno but found more in Asakusa near the Sensoji temple. One day we purchased a JR rail pass (730 yen) to hit the main areas around Tokyo (Shinjuku - great pastry shop just outside the station, Harajuku, Shinbuya, & Akihabara) but this does not include the metro lines. Our second day we walked around Ueno park/Yanaka and purchased a round trip metro ticket to Asakusa (we did not purchase a day pass for the metro).
Credit cards were less accepted in Tokyo than in Kyoto which was surprising. You must use the post office for an international ATM which was a much better exchange rate than the World Currency Shop.
Overall I don't have any real complaints about this hotel, but I'm not sure that I'd choose it again.
