I stayed in Berlin for 5 nights during the Berlinale at Gili's apartment.

1. Gili is a great host, very helpful during the booking process, gave good directions to the apartment from the airport and was waiting for us when we arrived at the local u-bahn. Complimentary chocolate on arrival was well received!

2. The flat is perfect. Short walk to Hermannplatz. Bed was large and very comfortable, there is fast internet, large tv (we didn't use it, but it's there!), nice furniture, flat is warm. Shower is clean and warm!

3. The area near to the flat is a lot of fun. We found excellent places for breakfast, dinner and drinks each evening. Can recommend the following locally:

Coffee/breakfast: Katie's blue cat, Bully's bakery, five elephants, cabslam
Dinner: Santa Maria (Mexican, great cocktails also), Berlin Burger International (huge, delicous burgers), Gaston (great tapas), burgermeister (burgers, cool music)
Drinks: Das Hotel

Berlin is an awesome city, lots of variety. Do some research, pack comfortable shoes and enjoy!

All in all, only good things to say about the city and the apartment, it's a great place to stay and Gili was a great host. 100% recommended.
