We absolutely enjoyed our three nights in the Puna rainforest. The cottage was very cozy and had everything we needed.
It is located in a very quiet and peaceful area. If you want to see the lava and visit the volcano the location is perfect. It is also a nice location to just have a break and relax.
There isn't an A/C but if you leave the windows open the breeze is more than enough. You'll even need the cozy, comfortable blanket on the bed to not get cold ;) Just don't forget your earplugs for all the frogs at night.
