We stayed at Splendid HolidayHotel for 3 days (was supposed to be 4 but we had some visa issues) and loved our stay. The staff was incredibly helpful, booking us a great and very cheap tour of Ha Long Bay on less than 24 hours notice, helped print our visas for Cambodia, and had our laundry done while we were out. The breakfast that comes with the room turned out to be some of the best food we had in Hanoi, only beaten by the restaurant Obama visited in 2016. The hotel is about a block away from a ton of great coffee shops, 4 blocks from the Bia Hoi corner, and a 10 minute walk from the lake where you’ll find every tourist who has ever been to Hanoi. The street is very authentically old quarter. The room was very clean and comfortable, and we felt safe leaving our things behind when we went out. In short this hotel was a gem and we would highly recommend it for anyone visiting Hanoi on a budget.
