Andreas' home was beautiful and he was very responsive when we had questions or ran into hiccups. When introducing us to the home, he shared with us restaurant and site recommendations, many of which we followed through on and they made our trip that much more memorable.
A few areas that could be improved on: check in was delayed because he was late, it was unclear where check in was, the neighbors did not seem very welcoming and they left us a note about parking, and the balcony actually DOES NOT overlook the caldera. Rather, it faces the east. So, if you want to catch a beautiful sunrise, this is your spot. However, if you want to watch a sunset, you will not be able to see it from this location.
Overall, Andreas' friendliness and responsiveness made it a pleasant and comfortable stay.
