Spent four nights at the APA Hotel in Ueno in April.
I had read about temperature issues and hoped it would be better in warmer weather, but the AC only ran briefly, and the room was too warm for my son and me to sleep comfortably.
The room was small (expected) and generally well-equipped, but the TV was poorly placed and only worked via casting, which didn’t function with major streaming services on an iPhone. We ended up not using it.
The hotel’s location is fantastic—lots of restaurants and shops right outside, close to Ueno and Okachimachi stations, and easy walking distance to Ueno Park and Asakusa.
The biggest disappointment was the staff. While friendly, they were inconsistent in handling typical tourist questions. For example, two trainees recommended a luggage service that would leave me without bags for 1.5 days, while another staff member later suggested Airporter, which got my luggage to the next hotel the same day. I understand a trainee might not know about these services but expect that they would ask their colleagues.
The lack of temperature control in the room means I would not stay here again but if this doesn't bother you, the location is great, room is small but well equipped and clean.
