We had a great time in Berlin. The apartment was perfect and very accommodating to our children. We were traveling with our 2 year old son and 5 month old baby. Everything needed for children was available in the apartment, from toys, to baby cots, child seats, and even bips and cutlery for kids. Both our kids were happy and filled their time in the apartment with all the toys available when we were not going out, which was perfect for us parents to take a break and plan our trip. The place was nice and cozy and we believe it was perfect for our small family. Even the fact that it was on the 4th floor was not a problem. My son enjoyed counting the stairs going up while for me and my wife it was good exercise. Location was also perfect as it was conveniently close to all the public transportation. The S-Bahn and U-Bahn train stations were just opposite the apartment while the bus stop was just walking distance from the place. Not to mention it was really close to the Charlottenburg Park, which connects to the castle, a beautiful place to take the family for a nice walk and let the little ones run free and enjoy nature. For those not choosing to go out, there were nice collections of movies, music cd's and books to enjoy while chilling in the living room. The host (Anton) was very nice and accommodating to our requests. We really had a good stay and will definitely choose to stay here again the next time we come to Berlin :)
