My wife and I stayed at Zyzy's apartment in Charlottenburg (Berlin) for a week. I was attending a conference held at the Convention Centre in Berlin Messe Sud, 2 stations away on the S-bahn. We had previously travelled to other parts of Germany on holiday.
The apartment was convenient, as it was close to the Chalottenburg S bahn station and the Wilmersdorfer U bahn underground. It was about 15 minutes by train to Berlin Hauptbahnhof and Freidrichstrasse stations in the heart of town, and the location of Berlin's major attractions. We found this location excellent. The bus from Tegel airport (109) also went past the apartment.
We arrived after a long flight on a Sunday night. Zyzy and her husband were waiting for us, and we had a seamless check in and explanation of the facilities in the unit.
Zyzy was always prompt in answering her emails, right from the time of the booking. She has limited English, but with a translation app, I was always able to send and receive any necessary emails to organise times of arrival etc.
The apartment was set up for us as a couple, but had another bed, and a cot onsite, so would be suitable for a couple with children or a small family group. Having been on holiday for several weeks, a washing machine was a blessing, and enabled us to stock up on freshly washed clothes. There was a drying rack which could be used on the balcony, or in the large living room. There was no dishwasher, but this was unnecessary.
The unit is on the 3rd floor. Access is on the level from the street, and there is a lift. We noted a wheelchair in the apartment, so disabled access is easy, but as the shower is over a bath, washing and toileting would depend on the specific disability.
Security is good, with keyed access from the street and garbage area, and a dead-latch into the apartment.
Charlottenburg is a working class and migrant area, and most of Berlin's major tourist attraction are a train or bus ride away. The public transport systems works extensive hours and is very efficient (buy a several day pass!) . The apartment is in a block mostly occupied by local families. The district's demographic means there is a wide range of dining options, including Russian, Chinese, Vietnamese, Japanese, Middle Eastern and Indian, and lots of vegetarian/vegan cuisine, as well as local German food. There is a 24 hour Russian supermarket at the station, as the area has a large Russian community.
The apartment was spacious, convenient and we were very happy with our stay. If you are not after a luxury, modern apartment in the heart of the tourist area, this apartment is recommended.
