We had a great stay at the Calypso. The lobby and rooms are brand new and the location is perfect - right in the middle of the Old Quarter. Even though this hotel is RIGHT in the middle of the old quarter, it's located on a quiet little pedestrian street, which made for comfortable, quiet nights. The staff makes an enormous effort to be helpful and welcoming; when we arrived at 11:30pm, the doorman and receptionist greeted us, took our bags, and brought us a hot cup of tea immediately. The breakfast is very good and the wait staff encouraged us to try to some authentic vietnamese favorites (which they will cook for you to order).
The staff is very willing to ensure that your expectations are met. They even followed up with us about our stay after we returned to the US. We have (and will continue to) recommend this hotel to friends/family traveling to Hanoi. Great value and memorable stay.More
