Hubert's place is well located - close to a supermarket and the Bio Company a short walk or only one Ubahn stop. Having the Ubahn right outside the apartment was great and we certainly got more than value out of monthly ticket. We were there in the big heat of August but with 6 large windows - open all day and night and a good fan we managed well and did not feel uncomfortable. Hubert was a delightful host and even when he was out of town he had good systems in place and we communicated when we needed to. There are 59 steps up the third floor but we got fit and we are in our 70s.!
