My friend and I stayed at Oli's studio apartment for a few days. We agree with all the positive reviews Oli received so far. We appreciated everything, including the quietness and cleanliness of the place, the nice balcony, the beautiful fresh flowers in the bed table, the yummy Lindt chocolate, water and bier in the fridge, the hairdryer and shower gel in the bathroom, the washing machine, the location near so many interesting places (the memorial church, Ku'damm, the Bikini mall, the Monkey bar and Neni rooftop restaurant, Tiergarten, Benedict for the 24hr breakfast and much more). Easy connection with public transportation (S-Bahn and U-Bahn). Oli was very responsive and was able to offer us a late check-out, which made our lives easier. There is a direct bus to Tegel Airport. In short: we highly recommend Oli's place.
