Pros: Internet was quite fast (250mbps with an Ethernet cable) and the room was clean.
Cons: they have an issue in communication. I had to ask same questions again and again as they don’t really read through or get them. Also it’s a quite bit of walk (15mins) from Asakusa station (Ginza / Asakusa line). The room was smaller than expected and neighbors can be pretty noisy. AC was kind of broken too.
