The location is great. The ASAKUSA line A2 exit is just a corner away. If you're taking skyliner to Ueno, I suggest you taking the GINZA line and transfer to ASAKUSA line.
There are a convenience store and a small super market where you can buy some snacks and drinks. If you get hungry at night, Sukiya (24h) and McDonald's are few meters away.
It's really convenient.
