We had a nice time at Rene's apartment; the place was as advertised and we especially loved the kitchen which offers all the necessary appliances and more. Good location in Kreuzberg, with East Side Gallery just around the corner, Checkpoint Charlie in less then a 10 min stroll; the metro station is within 5 min walk and from there all other major sights are reachable within 10 min ride. Petra greeted us on arrival and gave us useful tips on getting around town.
The only minor thing we would suggest improving is the sofa bed in the living room, bit uncomfortable to sleep on. Nevertheless, would certainly recommend the place!
