Kalispera Helen and thank you for your reply. The house is located on the beautiful island of Andros. Believe me no one else has a Jacuzzi in the island, except some very expensive villas which have pools and jacuzzi (but the host more that 12 people). It might sound weird, but it is true.
My house has two bedrooms and it is like a huge apartment with a great sea view. My guests range from pensioners to families of up to 5 people. It is not a very expensive island, like Santorini or Mykonos and never was very touristic except for the last two years, where we had a 30% growth in tourism.
So I am thinking of be ahead of the competition if you know what I mean:):):)
We have 37 degrees C so a cold Jacuzzi would be a good option for me at the moment. Hahahahaha.
