Me and my sister really enjoyed our stay in the apartment. Kasia sent lots of useful info ahead of our stay and then Alan text us how to get to the apartment from the airport (which was v lazy of us and v nice of him). Alan met us at the apartment and was v friendly and helpful. The apartment was perfect, warm, cosy, safe and clean. Nice hot shower and good little kitchen to make a brew and a bagel before heading out. We did plan to use the sofa bed so we could have a bed each but the mattress and blankets on the bed were separate so was fine to share. ps the French place they recommend was lovely and imagine the other places they recommend nearby would be good too. Bargain apartment and loved Berlin!
