We have recently stayed in Luciano's apartment in Santa Cruz and I have to say it was a very pleasant stay. It was our first AirBnB experience so we were a little bit worried but we did not have to. Luciano responds very fast, he is a really kind and helpful person (even though we have seen each other 3 times maximum). The apartment is very clean, spacious, we shared it with one guy, so practically we had it all for ourselves. It is situated in the middle of Santa Cruz, you can get everywhere by foot (but lots of hills everywhere :) ) but I definitely recommend taking a car to see the rest of the island. So do not hesitate to write to Luciano, you will definitely like it!
