Fantastic apartment in a really great location. We arrived a little earlier than the stated check in time but we were able to get access to our room after a short wait while it was cleaned, which we really appreciated. Desk staff spoke excellent English. Room was clean and well set out with a spacious bathroom and well-equipped kitchen. Location was also really handy, right next door to the Landsberger Allee S-Bahn station and only a short walk to the tram stop and local supermarket giving us a great base to explore the city. The only thing which could improve the room is the addition of an air conditioning unit. Our room was quite warm at night (despite the sub-zero overnight temperatures), meaning we had to open the window and because of this we were woken at times by tannoy announcements and trains arriving and departing from the nearby S-Bahn station. Hopefully this can be sorted soon. We're really looking forward to staying here again the next time we visit Berlin!
