I had a long stay at this hotel, and it was a great place to have as a "home base", the staff was kind and courteous, the room was functional, I had the widebed room, and although the room itself might be a little small for some, it was a perfect size for me and also has good soundproofing, there was a construction site next door, but I would only notice it was there when I went out of my room.
The hotel also has a vending machine, microwave and a coin washing machine.
It also includes a good breakfast of mostly bread, but they also had a protein, like chicken or pork,yougurt and soup.
The best part was the location, it is about 3-5 minutes away from the Ueno Station JR Lines via the Panda Bridge.
About 2-4 minutes from the Ueno Station Tokyo Metro lines(Ginza line, that goes to Asakusa and the Hibiya line).
Also about 5-7 minutes from the Ueno Keisei Station, in case you are arriving/leaving in the Keisei Skyliner train.
All in all, I had a great stay here, and would stay here again should I choose to stay in Ueno in the future
