My stay at Alex's was wonderful! Wife and husband are the kindest hosts and are willing to help all the time. The room is so roomy, much bigger than I thought. The beautiful high ceiling is a plus. I was busy with the daily activities, if not, I would like to sit down on the cute balcony to enjoy the peaceful street view. The bed is also big and comfortable. The location is so convenient to the Brandenburg Tor by S2. It should be the best and the most affordable place you can find in Berlin. The neighborhood restaurants are also friendly and enjoyable. I will definitely come back again!
