If you walk straight out of the JR Ueno ticket gate, cross the street, then turn right at the major intersection, and then cross the street at the first crosswalk, you can get to the hotel without needing to go up stairs or through the crowds in Ameyoko. The hotel is one street back from the main road - I had no problems with street/traffic noise on the 3rd floor.
The kitchen is fully equipped with all three pots, pans, and cutlery you could need. The bath has a function to keep the water hot. Bed was reasonably soft. A bit expensive, but very convenient and good location.
