We didn't meet Roi himself but for his correspondence, he was very quick in replying and very accommodating about check-in and check-out times. His "check-in lady" Maayan was lovely as well and gave us some good tips about places to go out around Berlin. The apartment itself was the nicest of any AirBnB we had stayed in, the sauna was a nice treat after the cold winter days of touring around the city. Comfiest bed I've ever slept in as well!!
