The best way to check the lack of objectivity in this evaluation is the photo of the window, the one you say does not exist.
I could not receive you but my mother took care of it. If you had communication problems because of the language, you could have contacted me but you did not. Your way of comunication whit her was sending sms from a Dutch number. It is unacceptable that you require the host to respond to a foreign number incurring in high costs. However, my mother answered you by Airbnb page. The correct way to comunicate is calling the host or writing through the Airbnb page. Although it should be said that you had already agreed the place and time of meeting point... You have instructions in the loft in English, French, Italian, Portuguese and Spanish. More and more, you could have told me your problems to have solved them.
This humble space is characterized for the price and the cleanliness. It is totally untrue that this place was dirty. I have rented this place for two years and I have had always good reviews on cleanliness. The sheets and towels are of high quality and recognized brands... This is the cheapest accommodation in A Coruña and you paid the same price in high season and celebrations in the city. Next time, before reservate and evaluate a place, take in acount the value for money. You should demand by virtue of what you pay.
