We stayed in this cottage for the month of August. By North American standards, it is very rustic. We were initially disappointed: there was no one at the ferry to meet us (she was late), and upon entry into the house, we learned that the photos are more flattering than the reality: it's smaller, a little shabby, and not as clean as we expected. Nor did it have the Internet we had inquired about before booking; ultimately a router was provided in which we used our own data card.
However, overall it was a good experience. We pretty much lived on the lovely back terrace and enjoyed the simplicity of cooking on a hot plate in the outdoor kitchen. We were very grateful for the air conditioning to retreat to, particularly during a 37 degree heat wave. The location is fabulous, mere minutes to everything -- shops, groceries, restaurants and our favourite black sand beach. Volcano is a magical place, and we fell in love with its people.
