The best guided walking tour of Ho Chi Minh city

Was left disappointed and sad for our booking. The guide did not show at the allocated time and when contacted, did not respond until 1 hour after the tour was meant to starr, and stated it was cancelled, moving us to the following day without consultation. We could not go the following day as we already had plans, and did not wish to go on the tour even if we didn't due to our experience. Was very sad and disappointed as this is a highly rated tour and guide!
