Peter and his wife were great hosts, very friendly, ready to help and very responsive. Their place was perfect and well located near the U7 metro line making it easy to go anywhere in Berlin in a short time. Their place was very quiet, well decorated , very clean and with all the amenities. The three of us occupied the second floor of their house and had our private entrance. I was able to leave my car parked on the street safely for the entire week we were there.
I highly recommend Peter's place and will more than likely stay there again in the future.
