The place is very secure with a hefty locking mechanism on all private rooms. You won’t be disappointed in the security.
The whole place is well kept with a caretaker coming often to make sure the common area is cleaned regularly.
The place is situated near several train stations and quite close to Yoyogi and MejiJingu really, no need to take a train.
I walked to shibuya scramble often as it was only 30mins walk as that was the only destination area that It didn’t make sense to take the train, although there were buses that ran that route I loved the walk and there were many things to see along the way.
Only downsides of this place is there are about 6 private rooms in the place and if someone comes home late without being quiet you might get woken up. Also the place is near a freeway so there is a bit of a sound if you end up in the outer room near the freeway like I did, however the owners have installed a double set of windows.
Other than that it was an excellent stay.
