Lio & Ete's apartment was a great place for staying in Berlin. The apartment is spacious, very comfortable, gets a lot of sunlight and has a nice green balcony. Since it is a residential building with families with kids living, should be really careful with the noise, shouldn't be partying inside. The place is located very close a S-Bahn station "Sonnenallen", that takes everywhere in town. The area has several nice places for eating, e.g. at Sonnenallen or Richardplatz. Unfortunately, we couldn't meet Lio or Ete, but we found everything so well organised for our arrival.
