We loved our stay at the Fiddlehead House.
The location is great - 5 mins to the Volcanoes National Park gates. It is 3-4 minutes to restaurants (all 3-4 of them in the town.
The house is very nice - old but nice. It was clean, well appointed, quiet, awesome shower that could be converted to outdoors shower, heating and indoor fireplace.
The description here is accurate.
Now to my personal pet peeve, and this one is nothing against Fiddlehead House but in general on what AirBnb is becoming. After paying a lot of money for cleaning, the expectation is that we would clean our dishes at departure. And there is no dishwasher. That feels wrong - like Nicole and diming.
