Our rental car company would not rent us a car because they would not allow their cars on the road that Sifnos Residence was located. We found another company that would but explained that the place was on the side of a mountain and the road was extremely steep and no guard rails! I reserved the residence because it advertised that they had WiFi which they did not! Also they told us that we couldn’t do our laundry in the machine, which was also advertised. We were extremely disappointed, and since I had travel insurance we almost left. It really ruined our trip to Greece! All of our other hotels were fantastic, but this one caused us so much stress! I tried to talk to the lady, and she was so rude and unhelpful! I will never go by the advertisement again.... I will research and use word of mouth! Our friends stayed in a place in Karmes, Sifnos and we almost went to stay with them! Extremely annoyed by the whole situation! Thanks for asking!
