I stayed at the Crown Hills Hotel Ueno for six days. The room and bed weren't particularly large, but they were above average for a hotel of the same price. The room was quite clean. The bathroom and hot water were excellent. It's equipped with air conditioning, an air purifier, and a water heater. The location is strategically close to JR and Metro stations, as well as the airport train. It's also conveniently close to Ameyokocho Market and two stations from Asakusa. I would definitely return if I ever return to Tokyo.
