Comfybed Ginza was ideal for my situation. All I needed was a room to work in-between meetings in Tokyo, a decent bed, desk space, personal shower/bath, that was close to stations. For business travellers or someone who just needs a private bed to sleep in for a few nights, it's great for the price.
The room had a comfortable bed, its own unit bathroom/toilet space, desk by the window, overhead TV (which you can use with your Netflix account), a mini fridge, kettle, and a space to hang a few items of clothing and put a small case. (Squeezing in a large case into the room could be a bit awkward). I didn't use it, but there's a communal kitchen somewhere else, too.
