Duc Son was very welcoming and he always replied quickly. The apartment is bigger than what it looks like in the photos, but the furniture is simple and minimal. The kitchen was equipped with the essentials, but it wasn’t too practical. However, we were able to cook 4 meals so it worked out for us. The heating worked perfectly and the beds were comfortable. Although the apartment isn’t near any turistic attractions, it is next to the M2 tram station, that arrives every few minutes and after a 10 min ride you’ll be in Alexanderplatz!
