I have stayed at around 15 hotels in Da Lat and He boutique will be on my list of favorites.
Boutique hotel so the decor is beautiful, the rooms are clean, the water is strong and hot quickly, the location is right in the center so it is close to everywhere, the hotel has a self-check-in style - quite interesting, if you need anything just text the 2 owners. The 2 owners are very cute and polite.
