I'm in Da Nang now until mid June there's enough positives that I'm thinking about moving here. Or I can keep my Condo back in Thailand and spend most of my time in Da Nang. I don't mind travelling back and forth a few times a year it's like the best of both worlds.
It's definitely cheaper here, a lot less unstable farangs, better restaurants, excellent service, very few issues with traffic, beach walk is a thousand times better than Pattaya/Jomtien. Pollution is bad in both places but I think it's worse in Bangkok/Pattaya than Da Nang. Drivers license isn't an issue, at least for motorbikes.
People definitely a lot skinnier here, makes for a much happier atmosphere. Less bad attitudes towards farangs that's for sure. Weather wise it's got a much cooler winter here and the rainy season is from Sep-December. Those are the months I don't want to be in Da Nang.
Somebody told me the other day that Vietnam prices are similar to what Thailand was 5-10 years ago I think that's about right.
