Beware: this is going to be a long post. We also had a million pictures we wanted to share and quite some trouble blogging because we didn't take a laptop with us - but here's what we came up with.
Before we left Germany, we looked for a guide to HCMC via Couchsurfing, so we wouldn't be too lost in this big city and foreign culture. We got in contact with Cuong, who agreed to show us the city and (very important to me!) introduce us to the local food. We could definitely not have found a better guide. We were picked up at our hotel by Cuong and his wife on their motorbikes (I guess I would call them Scooters, if I was in Germany, but here it’s used for both) and then had a glorious day exploring HCMC.
