Lena's apartment is well-designed and I had a nice stay with my parents. Lena was very kind and responds quickly. So overall it was a nice apartment. The water kettle did not work on the forth night. And it caused the whole electricity down. I called Lena and she talked to the apt manager so that the problem was fixed in an hour. However, the water kettle cannot be used anymore and Lena didn't response my further question. So we had to make tea by using the pot to boil water... Also, the balcony is full of bird poo... So I cannot even open the door. Overall, the apartment is quite nice but needs some improvement as well. Thx Lena!
