We camped here, the showers are cold, toilet you must have your own paper. The door doesn't close to good in the shower either. The people are nice & there is a large grass area to camp on although a little open. Pets would do Ok here as they wouldn't be lonely as there are a number of dogs here (they are friendly tho)
From Ndende, the road immediately turns into a poorly graded piste to the border. This continues after the border all the way to Dolisie, with a LOT of bull dust. This road could be a bit difficult in the wet season.
There is also no fuel between Ndende and Dolisie so it's worth fueling up, though you may be able to buy bottles of fuel from small villages along the way.
We camped on the lawn and paid 2000, rooms are for 5000 cfa, probably negotiable. Dirty ablution, bucket shower, lots of sand flies, but nice hosts and nice scenery. Not sure that better than bush camping.
