This was our mistake in Luang Namtha. Three kilometres far away from the centre with no restaurant. Nice views but SO dirty. The place is quite abandoned, it seems nobody is taking care of it anymore.
There are many other options in the city: our last night, after having dinner in the night market, there were no available tuk tuks in the city and we had to walk 3 kilometres under the rain. Nice guesthouses are just in front of it, we almost booked a room to avoid the rain. Did I say it was dirty? It was!
