I stayed in this apartment for one week. It is very spatious and nicely decorated. It has a separate kitchen and a big balcony. The sofa is very comfortable and can for sure be used for sleeping if many people were staying.
The neighborhood is very safe, with lot of restaurants nearby. Metro sattion is about 5/10 mins walk and from there it is just 5 stops to the city center.
Angelika is very atentive and will respond quickly to any question you could have about the apartment.
