6 of us had a great stay in the apartment. it's large and very clean, and the location is just a 10 minute walk from Alexanderplatz! The hosts replied very quickly when we had any queries, and sent someone over to look at the heating right away when we couldn't figure it out. The only two small issues were the fact that one of the bedrooms is also the living space, and the shower holder is low down which makes showering a bit awkward. Would definitely recommend it overall!
