Communication with Thuy was easy and she replied all the messages fast. We had the check-in/out without any problem. The room was clean and we had everything we needed. Also, there was a mini fridge in the room. Internet connection was good, too. We had a pleasant time in the home. The location is not at the center however there are many tram connections to different directions among the city. Close to the flat, there are many shopping options. On the night, the outside can be noisy sometimes... The only thing we did not like was when we were out of soap. I informed her about this however she didn't fill up the soap bottle. And, i needed to add water to have some soap after using bathroom for 1-2 days. In general, I would recommend her flat for accommodation in Berlin.
