Not the best first impression when my Vietnamese friend phoned them up to make the booking - the first question that the hotel asked was "are you vietnamese or foreign?'. My friend replied Vietnamese (they are, I am not) the hotel replied 'we dont have vietnamese staying here, only foreigners' and promptly finished the conversation. A big rip-off red flag.
Despite this I went anyway, as Dreams wasnt available and there was a good online discount. Hotel is quite a long way from any of the places you would want to see, so they have a couple of motorbikes that can be rented. If you want to see the city, you will have to rent these, go on a city tour (I would suggest booking this in a city centre agency or you will have to pay double booking commission to both the hotel and the agency) or be prepared for quite a hike to see any of the sights or find a nice restaurant. Da lat is a beautiful city, this hotel didnt help.
Not a disastrously bad place, but unfriendly and inconvenient, wouldnt recommend.
