Playsis is an excellent option for either the short or long-term traveller. The rooms are supremely clean and comfortable to stay in, with very little noise from outside. The staff are incredibly kind and helpful when you need them, but otherwise completely unobtrusive. You're right on the doorstep of Asakusa, and there are a lot of amenities close by, as well as a couple of metro lines within a 5-minute walking distance. I would definitely recommend staying here (a complete bargain for the quality of service).
