This is a great hotel overall.
It's probably better for people travelling alone as the rooms are small and may be awkward for two people to move around in. Despite the small size, the room had everything I wanted and the space was very efficiently laid out.
There's a desk with multiple outlets, extra outlets around the bed, a mini-fridge for storing cold items (even food, as I think there's a microwave on the second floor), hangers, and lots of space under the bed to store your luggage.
The room has a very large TV placed at the foot of the bed. Each room appears to have its own Wifi access point so I never had any trouble with connecting my devices or using the Internet.
The bed was decently sized, but I will warn people that the mattress is firm, and the pillows are also much firmer than most westerners are probably used to.
This hotel is very, very close to the JR Kanda station for easy rail access to the rest of the city, and is also close to a Metro line. There are at least five convenience stores within five minutes on foot if you need anything. A slightly longer walk straight north will take you to Akihabara in about 7 minutes if you are bored and want something to do.
The staff are great and everyone I interacted with spoke enough English. They were also kind enough to hold my luggage for me on the day I checked out as I had a late flight home.
Top notch place to stay.
