Ok, bottom line: the stay was amazing!
I came with my family for almost two weeks to visit UCSC, and the location was just great for us. I could go to the University, while they spend time on the beach or around. The house has kitchen and washing machine, which was really prefect for us for such a long stay. Khristina was great, she helped us a lot, recommended really good places to visit and was available by phone/sms for any questions! The house also has parking (it was important for us as I had to drive a lot!)
We will definitely come back!
