Noi Bai International Airport is the international gateway of Hanoi capital and Vietnam in general. There are a small number of hotels for you to choose from, if you would like a place to rest. Some familiar names include: Noi Bai Airport Hotel, Melinh Hotel. You can choose from these 3-4 star hotels as you prefer. Most of them are big and modern. Some have ideal location at the expense of comfort.
The quality of facilities and services at these hotels are promisingly advanced enough for both domestic and foreigner travelers. The number of rooms is quite big and the rooms are divided into 3 classes: standard, superior and deluxe. The price is about $41 and up for a decent one. Each hotel is clean and maintained everyday - good look, good smell, good for health!. The staffs are friendly and helpful.
From these hotels to the city center, it takes about 30-40 minutes. Expect some noise from the landing aircrafts in the airport nearby. Overall, they are great for a short stay but if you do not mind a short commuting time, you can head to the Westlake area for better hotel choices.
