9.8/10 Exceptional! (316 reviews)
I believe the description for the hotel foods it justice it’s way better. The hotel and rooms are great and the area around the hotel is safe and easy to navigate. The hotel is s short walk to super markets and convenience stores and a major shopping and dinning area. And close to subway station. Very good accomodation to stay with kids.
