We recently had a 5 week holiday in Vietnam, starting in the South.
Custom Vietnam arranged a short private trip in the north of Vietnam. Over a couple of months during the planning phase Julie, the agent who arranged everything for us, was helpful, professional and always gave speedy responses to all the many emails we sent, checking details and making helpful suggestions. Julie was great at customising the trip according to our interests and physical ability and suggested a number of 'soft' treks for us when we were in the mountains! We drove to Sapa in the North west for three nights with a great personal guide and a very safe driver. We had a night either side of this in a hotel in Hanoi - suggested by Julie - and it was excellent.
We finished with a fabulous cruise to Bai Tu Long Bay for 1 night with an excellent cruise company which Julie suggested and arranged.
Julie also managed to book us overnight train accommodation from Ho Chi Minh City to Danang when we were having difficulty booking it ourselves because out trip was coinciding with the build-up to Tet.
Julie was incredibly friendly and helpful, giving our trip in the north a delightful personal touch. I would have no hesitation in recommending this company to anyone wanting to travel in Vietnam in the future
