The apartment is exactly as you see on the website, very clean and offers three distinct sleeping rooms. The apartment is well equipped (warm water, TV chanels, wifi, kitchen, etc...) and everything is working well.
We enjoyed the calm neighbourhood. Perhaps not the most exciting area of Berlin but with a lot of green and a large park next to Fai's place. Subway's connections are very easy from there.

On the arrival's day, Fai welcomed us and provided us with some useful information (including maps and subway's plan). If you have little kids, they surely will appreciate the rabbits running freely in the garden at the bottom of the building!
