Overall, there are many great things about this property: 1) wonderful location in relation to the town; 2) private terrace w/ wonderful view of ocean/caldera; 3) responsive host. Also, the terrace (which is not directly connected, but just a few yards outside the door) offers privacy from onlookers on the main pathway above, unlike many of the more luxury accommodations we saw with mini jacuzzis and private balconies, where you are literally able to see guests from the path or restaurants above.
Just a note (not criticism), I didn't realize that you cannot see the sunset from this location, but it is a very short walk to the area where you will be with hundreds of other people to view the sunset. Just a fair warning that if you have mobility issues, in addition to various stairs on the pathway from the drop off to the property, reaching the house requires going down some steep stairs. Luckily, our host kindly carried our bags down, and we paid 5 Euros each bag to have them carried up and to the transportation site.
As mentioned, the shower is small (think cruise ship cabin shower), and water did get on the floor, but depending on how many days you're staying, that might not be an issue for you.
