There were no bad experiences. The highway was very busy and noisy when I checked in, but the owner assured me it would be much quieter at night, and she was right! Like a lot of motel/hotel wifi setups, the band width could have been bigger for work, but was otherwise okay for personal use.
I stay at a lot of motels or hotels in BC and I really liked this place! Cranbrook is not that big so location doesn't really matter. It's an older motel that has been upgraded, with all new furnishings, facilities (small fridge, TV), beds, and bedding. It was very clean and fresh, and it has a good air conditioning system that kept my room nice and cool the whole week I was there, without any stuffy, closed in feelings. I didn't sit out on the balcony much, but thought I should have when I did.
