We booked the Chi Hotel to try another local luxury hotel in Hanoi. Unfortunately, much of the hotel was under renovation giving areas, including the hallway a dirty, dark feel. Great location near Ho Hoan Kiem Lake, 1/2 block from the Cathedral, restaurants, shopping and other sites. Part of the reason we booked was for the rooftop bar, that had a view of the Cathedral, but the restaurant/bar area didn't feel quite up to par with luxury. So even though our room was clean and comfortable and service excellent, I'm giving it 3 1/2* due to the renovation on this visit.
5* Service: Excellent. Lily spoke impeccable English, was responsive and very helpful in arranging transportation for 5 people (2 stops) from Cat Ba Island and again to the airport. The bellman took off his shoes when bringing our bags into our room!
4* Rooms: We booked the Superior Plus room which was spacious, quiet, clean and comfortable. The bed was comfortable, AC worked well and the bathroom was large, with a nice shower and tub. Unfortunately, the view was to another building right next door.
