I'm afraid that I have to deal with an unfair review, as you complain about amenities that you knew that were not provided before booking. The house listing clearly mentions that there is no wifi, washing machine, or electric kettle at the moment. It also informs about the existence of staircases which are difficult for toddlers. I'm afraid it is your responsibility to read any house description before booking so as to make sure that you choose the right place for you.
However thank you for giving me the chance to mention the following: As I explained to you again in person, the house is a recent construction and thus, it will have internet connection within 2018 season. The electric kettle is a good idea, I have already added one to the kitchenware. Thank you for pointing out any drawbacks of the house staircases, I will take your feedback into consideration for any future house or listing amendments, as it is my first priority to help my guests feel like home and enjoy the time they spend in my house.
