Two days in Saigon might be enough for Saigon (unless you have friends there, as we do now), but it's the rest of the country that's fascinating. We found my wife's old house, where she lived for a few years before she came to the US. We saw the old cathedral under renovation so we couldn't go inside.

Be careful about markets in the morning... especially if you're one of the first customers and you don't buy anything. They take that as a bad omen to start their day. Thanks. Good advice that I have not seen anywhere else.

You're staying just a couple streets away from where we stayed, at A25 Nguyen Trai, across the street from a Catholic church "Nha Tho Huyen Si".
