“In my opinion, this four-star hotel is a solid choice in Hanoi's Old Quarter, with its full-service spa being a standout. I noted the proximity to attractions like Hoan Kiem Lake; ideal for tourists wanting to explore. While the location is central, I would advise light sleepers to pack earplugs as the area gets busy early. I think the customizable airport shuttle service is a practical touch.”
