I went to Hanoi with my wife and adult daughter. I booked 4 different hotels 4 months before our trip. 2 weeks before we flew, I narrowed it down to Hanoi La Siesta in the Old Quarter because it had a spa and a hotel rooftop bar (cigar smoking allowed!) and most importantly, our guided tours were walking distance to.from the hotel. The staff very attentive and professional staff. We checked in close to midnight. The hotel booked us a private large car from the airport to accommodate our bags (12 days + wedding). I was afraid that our "windowless" room was going to disappoint, but I was wrong. The modern rooms were next to each other, one queen bed, one king, offered plenty of space for our stuff. These hotels aren't tall, and they are built right next to another building so at most if you had a view, you would hear the local traffic and look out into the busy street way. Windowless was a welcome, because our sleep was never interrupted by noise or the impending morning sun. Breakfast buffet was pretty good, custom eggs, pho, in season fruits, Vietnamese coffee. If you are expecting to fill up at the buffet, you are going to never be hungry for the amazing street food Vietnam has to offer. BTW, if you order bottled water or a can product, you will be charged. Spa treatments were great and inexpensive. Rooftop bar was relaxing and had a great view and drink specials! Did I mention the staff was amazing?! They even walked us to exchange our USD at a jewelry store.
