Communication with Andre or his deputy respectively was very clear, fast and friendly. Check-in went fast and smoothly.
The appartment is very good located - ca 5 minutes of walking to S-Bahn, or you can even walk through the Tiergarten directly to the Brandenburger Tor (30 - 40 minutes). Rewe supermarket is located ca 5 minutes by feet.
Parking on the street is charged 2 € per hour from 9:00 to 20:00. We used Park One Tiefgarage (Turmstraße 26) for 10 € / day located ca 10 minutes of walking.
Furniture in the apparment is older (more used) than it looks on the photos. On the other hand it was clean as well as bathroom. Considering the price and location of the apparment it is acceptable.
But there was one thing that made our stay quite unconvenient. It is the quality of air within the apparment. There was an intensive smell of something unpleasant. We think it might have been a naphtalene (insecticide against moths) that comes out from an old wooden wardrobe in the sleeping room. We strongly recommend Andre to remove this piece of furniture or source of smell respectively. To be honest for our next stay in Berlin we would rather look for another apparment to avoid that smell.
