First, Tim's place is gorgeous and super cozy! When you walk into the kitchen and living room, you have to take a minute to soak it all up. Huge ceilings, lots of light from all the windows and a kitchen people can only dream of.
I came to Berlin for work but when I wasn't working, I really enjoyed just being at Tim's place sitting on the sofa and reading a book. I'm actually looking for a permanent place to live in Berlin and if I could, I would replicate the kitchen and dining area so I can have that nice cozy feeling.
Location-wise, you are RIGHT next to a tram stop which was super convenient for me going to work and also to the gym. Also, just down the streets is one of the major U-bahn lines making it really easy to go in the north-south direction if needed. If you are a foodie, you MUST take advantage of a couple of streets nearby where you can get authentic Turkish food and not the Germanised Turkish food you find mostly in Berlin. The only problem is, once you have the real-deal here, it's hard to eat Turkish food anywhere else in Berlin :)
Great great great place and I high recommend it if you not only want a place to stay, but you want the home-like cozy feeling. Tim is also super nice, easy to communicate with and the place was mega clean and welcoming.
