I was in Dai Lai Lake for two nights and found my stay at the LakeSide Dai Lai Hotel to be really comfortable and relaxing. You get a towel when you check in and coupons for breakfast. The staff was great. They helped me book a trip to Halong Bay and offered to keep my luggage for me while I was away. They also helped me book a train ticket to Hue. Also, they never turned on the a/c and only had fans on. The nights were cool enough that the a/c wasn’t really needed, but the first night was a bit humid and the a/c would’ve made it more comfortable. Overall though I would stay there again if in Hanoi and recommend it to others!
