Stayed only the night after visiting Universal Studios but wished we stayed the night before as well. J Hoppers staff spoke English very well, were friendly and clear in their instructions.
There is a small range of food options that can be bought on site and the shared kitched is very well equipped. Convenience stores like Family Mart, are not far away either. Loved the free tea and coffee service.
We had a private twin room with plenty of power sockets for recharging phones, etc. Beds were traditional and expect it would take a while to get used to the small pillows.
As its a hostel, we expected the request to strip the beds of linen and put into laundry hampers which was no problem.
Luggage can be forwarded there if you are organised or left there while awaiting for room readiness. Our room was ready earlier than expected so we were given access to it hours in advance which was much appreciated.
Note that there is no lift so carrying a heavy suitcase upstairs may be a challenge.
We wish there were J Hoppers everywhere.
