The room is much bigger than my expectations. The apartment is easy to reach by underground and buses. It is located at the place that I can reach Berlin Main station in 20mins by underground, reach Sony Centre in 20 mins by bus and Tegel airport in 40mins by underground. Very convenient.
There is a department store with super markets near by , less than 5mins walk. I can make by breakfast during my stay. For restaurants and kebab shops, they are within 5-10mins walking distance.
Though a main Street is just in front of the apartment, it is amazingly quiet at night time. It starts the busy traffic at 8-9am which can wake you up to start a new day. That is really good as I will not stay in bed too long and miss my sight seeing spots.
I will book this again in my next visit.
