Albert's apartment is amazing. We were privileged to rent it during one of the hottest months of June and we really enjoyed the air conditioner - to the best of my knowledge this is one of the only apartments that has an air conditioner in Berlin - a true advantage!! The apartment is immaculately clean. Equipped with everything you need for a long and short stay - we were there for three weeks. One of the most pleasant apartments I have ever been to. Great location - public transportation just below the house, very well connected to anywhere we wanted to go. Albert is kind and charming host and available for any question and request. Highly recommend!
