Summary: Spotless, incredible staff, quiet, and no rooster!
Details: The room was extremely clean, quiet, and an actual soft (quite a rarity) comfortable bed. The breakfast was a good mix of Western and Vietnamese options; and the specialties changed daily.
My favorite part of the hotel, however, was the extremely kind and helpful staff that really go above and beyond in accommodating their guests. The front desk staff of Ann, Kate, Molly and Elsa all helped me out during my stay. Whether it was to help me choose a tour and get the precise itinerary option (I'm picky) and suite I requested; to personally walking with me to the pharmacy and helping me get the proper medicine along with translating with the pharmacist when I ate bad street food pho (It was still tasty, at least.) There's a reason why I, and so many other reviewers speak highly of them, and I agree 100% wholeheartedly.
I stayed here for a total of 5 nights; as I booked a tour to Ha Long Bay with the front desk and came back from a solo 2 day journey to Tam Coc. I initially was only going to stay 2 nights but am very happy to have stayed as long as I did; as Hanoi is a fantastic city as well as the center point of the northern sightseeing triangle of Ninh Binh/Tam Coc, Ha Long Bay, and Hanoi itself. You could even include Sapa.
All in all, you will rest well here, rooster noise was almost non-existent, and the location to walking to many hot spots is usually no more than a 10 minute walk. Fantastic!
