I don’t think I’m much help haha. We didn’t plan nor did we do any intense research. All the cafes we found were on the way to our airbnb or on the way to where we were going. Honestly Vietnam is so modern now that there’s a cute cafe in every corner. I find its best when you just stumble upon a place instead of spending time trying to figure out how to get to a certain place.
We stayed at one of Harry’s residence airbnb in Hoan Kiem. They have a few in that building and we stayed in the one bedroom and it was super nice nice and clean with cleaning service included.
