My girlfriend and I stayed for 5 nights at one of Nikos wonderful cave houses. Nikos welcomed us very warmly and told us everything we wanted to know about his beautiful island. The Apartment was very clean, well equipped and WIFI worked fine. Nikos also helped us to rent a cheap scooter and was always open for our questions.
We had a wonderful stay and would be cheerful, if we can visit Santorini again!
