I booked 3 nights in Blue Hanoi Inn. The staff were so friendly and accommodating -- the general manager was up in the restaurant greeting guests and helping with breakfast the first morning, and the sales manager sat down with us and helped us book three great tours (street food walking tour, one day tour of Hanoi + visit to the ceramics village, and one day tour to the old capitol + boating and cycling around the countryside of Ninh Binh -- all of which we enjoyed thoroughly. The location in the Old Quarter is perfect -- walking distance to the shopping district, Hoan Kiem Lake, and good restaurants. The rooms are very nice and modern, the breakfast was amazing (you would easily pay more for the breakfast alone in most hotels in US or Singapore than the entire per night cost of the room including breakfast here), but I can't say enough about how great the staff were -- especially general manager, Harry, and sales manager, Nancy. Would definitely stay here again! :)
