I had a wonderful 3-nights stay at Hanoi Aria Hotel & Spa. The staff there is very welcoming, attentive and speak good English. They have a 24-hours front desk, so it ' s a perfect option if you are arriving to Hanoi late time. The room was comfortable enough, clean, and shower had a hot water with a good pressure. Location is 5 minutes away from the train station, which is perfect if you are heading next to Sa Pa with a night train. The only thing I would suggest them to improve-is to provide a thick enough blanket.
