The place is very convenient, Ubahn Station is about 30m and there were two supermarket nearby. We came from Tegel airport with X9, only 15 min and the bus stop is nearby.
There is a lift for every one and a half storey. The garden of Charlottenburg is nearby and we went jogging or walking everyday.
The host is very nice and she will be willing to meet my request. When I booked here, I didn't know tha hairdryer wasn't availabe, but I told her that I came from a country with 110V, and it wouldn't be practical when i bought one here in Germany that was no use to me after that. She said she would put one in the house.
Also my return flight was 18:25 and I asked her to do me a favor. She was more than willing to let me check out at a later time than at 10:00.
I recommend this place, what else is more important than after a long day sightseeing that the apartment is just a stone's throw away from the Ubahn 7?
