First of all the house is totally awesome. We really enjoyed to stay there. It was very comfortable and stylish. They are very helpful. A friend of them showed us the home and he was very helpful, too. There was only one key, it might be great to have more than one.
The house is located in a calm and nice neighbourhood. It costs around 30 Euros to go there from Tegel with a taxi. It is not very close to centers, but definitely not far, too.
Most of the things that people need are already in the house. Towels, bed sheets, pillows, kitchen equiments and etc. All of them were in the house in a clean condition. Only missing thing was the soap in the bathroom. The house has a very nice sound system that can be listened from the all parts of the house including the bathroom.
I completely recommend that place.
