We stayed at Stefan's place for close to 3 months for medical care. We had a great experience both with Stefan and with the apartment. We were grateful to be there. It is located in a well-established residential area.
We really liked the little balcony that overlooks the courtyard. Since you are on the 4th floor, you can open the sliding door and let the breeze in and no one can see into your apartment. There are several grocery stores within 3 blocks. There aren't a lot of restaurants nearby, but there are a couple of Italian restaurants and a great German restaurant as well as a bakery. Other restaurants can be found a little farther away. There is a tram stop about an 8-minute walk away; a bus stop 5- minutes and the U4 about 10 minutes away. The S is about a 13-minute walk. You can easily get to the city center on any of these.
The apartment is very nice. It's perfect for 2 people. It's very clean and modern and seems brand new. The kitchen is very small and if you want to cook, it takes a little juggling but can be done...I did it for 3 months! The laundry room is in the basement. It is coin-operated and a load in the washer costs 3 euro and the dryer is 2.50.
If you're looking for a quiet place to stay in a nice neighborhood, we highly recommend Stefan's place.
