I stayed at Triple E twice. Firstly for 5 nights in a balcony room at the start of a trip to Vietnam, and secondly overnight in a basic room at the end.
I enjoyed my stays. The staff were friendly and helpful. They keep a bag for me when I disappeared to Con Dao for a week.
For most of the time, the Wi-Fi wasn’t great, but still ok to do basic stuff.
The ground floor bar came in useful (!) a couple of times, although the first floor restaurant is currently closed.
The balcony room was comfortable but it’s only a very narrow, Juliet style balcony - not somewhere you can sit out on.
The standard room is fine, but no window. Personally I don’t like windowless rooms but they’re ok for an overnight stay.
