This is a super late post, but I thought this info would be useful for you guys.. Had a chance to visit Medan some time ago for only one and a half day. While work was the focus, I had been meaning to have a little leisure while I was there. Medan, for me, is a place to indulge my taste bud, so many good food there. So I checked around from a travel apps for hotel to stay one night. Then I found Grand Aston City Hall Medan, it had this Aston Spa room available, it looked interesting. I was hooked by a picture of some kind of sauna or an onsen in that room, is that even possible? That room must be very expensive. I checked the price, it was around IDR 900k (I booked on weekdays – I checked nowadays it’s around IDR 1,150K). For that kind of facility, I thought it was still worthy, so I went with it. My trip to Medan was only for two days, I flew in the morning, then attended an event. Medan is such a beautiful city, and I have been a big fan of the hawker...
