The couple that run this guesthouse made our stay in HCMC painless. They showed us everything on a map, gave us great advice, recommended some great restaurants, and put us into a cab to the airport for a reasonable price.
The room was a bit run down, but good value for the money.
The guesthouse is in a very convenient location, if you come into HCMC by bus, don't take a cab, it's two minutes away from where the buses stop. All the main attractions of the city were walkable which was great.
