Hosts were very nice and helpful about visiting Berlin, they send us a useful guide to the city and the same guide was left in the apartment. Kasia&Alan let us check out a little later, so we could see more Berlin. ;) Apartment looks really nice, it's clean and in a good area - there's a place to park in front of the apartment, it's at the border of The Environmental Zone so you don't have to buy the sticker to get there by a car. It's about 3 minutes walk to long opened shop, the 24h falafel&kebab and tram&train stations.
