The flat is big, in great condition with new and expensive beds. Julia seems one of this airbnb visitors without reviews and experience in airbnb, picky and who likes to complain in public(She never contacted me by private or by airbnb in the four days of her stay) After her holidays and living in Dubai, looks that She was expecting more luxury environment. What is not fair is that She tell me Im courteous and also difficult to get ahold in the same sentence. I was in my holidays when Julia stays in my flat, but even if I would stay at Helsinki, It would be the same, because no message in all their stay. You can see in my feedback from other guest that Customer service and my response ratio is 100%
Regarding towels there is like over 8-10 towels in that flat, so I see no sense in complain about one wet towel that maybe you took from dirty laundry. About sofa, there is old sofa so maybe there is some marks, but never something dirty or rest from a recent stay.
The price for 62m2 in ullalinna area that You have paid is even cheap, so please next time is better you go yo a 4 star hotel to pay 500 eur for two room for all your family in other hotel options, instead of 99/night that You have paid for this wonderful flat for 4 people.
