The venue was located in a very safe and quite residential area, with convenient access to two main subway stations (shinjuku & yoyogi).
We arrived early, but as the room was already ready, we could check in a bit earlier.
The room was spotless, and the beddings and mattresses were much more comfortable than expected.
The only difficulty was that our room was located on the 2nd floor, and with spiral staircase access. However, the accomodation staff helped us carry the luggage up so there was not much inconvenience.
Would definitely stay here again!
