Hi Mayya, thank you for your review. As there are many trees around, it is possible that you heard seagulls. I hope that you liked it. Although I hosted many families with babies until now, I am sorry that it was difficult for you with the babies. In fact, all the furniture in the kitchen (dishwasher, fridge, washing machine including small household appliances) are brand new! Regarding your allergy, I honestly don't know what it was. The apartment was cleaned before you came in and the sheets were clean, the towels also brand new.
