First of all, Betty is a fantastic person. She is very sweet, and answered quickly and accurately to all of our requests. The house is perfectly located and quiet, at 5-10 minutes to the most beautiful beaches. The pool is a real one where you can swim, which is uncommon in Cycladic Islands.
A few drawbacks: Internet connection was not working. The flatwares are missing for 5 people and are quite old (glasses, boilers, cutleries, etc), as well as the kitchen appliance. To get warm water, you must think about putting the heater on 40 minutes before and turn it off before using it. Cleanliness could be improved, we found an old shoe under the sofa and a lot of dust under every furniture (beds, sofas, etc). There has been no cleaning during our 15 days stay. This make the villa overpriced whilst those drawbacks could easily be solved. Without this, I would have put 5 stars for Betty's kindliness and the villa location!
