Our host was very prompt in responding to our request. We booked last minute and he was at the apartment within 15 minutes to let us in. He was SUPER accomoding, even sending over an iron and ironing board for us. The space is large and in a great location comparative to food and transportation. I have to say that given the price I expected a little extra attention to detail, but if you're traveling with more than 2 people like we were it's still totally worth it. We'll stay again next time we're in Berlin.
