We stayed at Julia's place the day we chose to visit the Volcano's National Park. I think it's well located for this purpose. Julia gave as some instructions to get there as well some advices about shops, market or restaurants as there were just a few of them.
The house is like you could see in the pictures. Our bedroom and the living room were clean and comfortable but the kitchen and the bathroom had old forniture and could be a little bit cleaner...
Wifi works perfectly.
I'll probably repeat for staying one night but not to spend some more days.
