de Ladda is quite possibly the best, most modern hotel in Mukdahan, and it is quite okay overall. Staff were pleasant, parking easy, good location for us, and right on the banks of the Mekong. Breakfast was passable (more so if Thai food is your morning preference).
The hotel build is very provincial (local standards). A lot was spent, but the finishing leaves something to be desired, particularly in the bathroom. There is only one bedside table and lamp (is there an assumption that in any given couple only one person needs a table/light?). And very thin walls -- can hear everything going on in the next room.
And, unbelievably, there is no furniture on the good-sized balcony overlooking the river. Don't ask me why...I just cannot understand this. Each morning we would have to carry out the (single) bedside table + a footstool and chair onto the balcony to have our coffee and watch the sunrise, and the same again in the evening for our sundowner drinks.
If we were to return to Mukdahan we'd likely stay here again, but only because there's not a lot of "upscale" choice in the city, and the view is delightful
