I stayed at Karim place for a month. Karim's communication was very professionally and effectively. He response to any questions I asked and also provide any documents we need.
The place located in a very useful location. 5 minutes walk to the tram. 10 min walk to U3. There are a lot of nearby store such as Billa, Penny Markt, Hofer, Spar and conrad.
I stayed in the room D34. The room have everything we needed even it was not refurbished yet. There are new beds, sheets, storage. The kitchen is fully equipped as described. We had a lot of sunlight hence the room is very bright. The space is SO HUGE! compare to the price. This room has the cloth washer inside.
You need to hike 3 floors but it is not too bad if you are in a good health.
